Purpose: Preservative-free cationic emulsion-based artificial tears (ATs) or drug vehicles are innovative eye drop formulations with tear film stabilization and drug delivery properties, and valuable in vivo anti-inflammatory and wound healing properties. These ATs have recently reached the market as ATs for the management of dry eye disease (DED) symptoms (i.e., Cationorm) or as a drug vehicle for cyclosporine (Ikervis). The aim of the present study was to explore the mechanism of action underlying the intrinsic anti-inflammatory and wound-healing efficacies harbored by the cationic emulsions of cetalkonium chloride (CE-CKC). Methods: The anti-inflammatory activity of two CE-CKC (0.002% and 0.005% CKC) emulsions was evaluated by assessing the expression of proinflammatory genes and the secretion of various markers in the following human cell types stressed by different agents: peripheral blood mononuclear cells (PBMCs; stimulation with anti-CD3/anti-CD28 or lipopolysaccharide (LPS)), CD4+ T lymphocytes (TCD4; stimulation with anti-CD3/anti-CD28), and a human corneal epithelial cell line (HCE-2; stimulation with LPS). The cells were incubated for 30 min with a 10% dilution of CE-CKC emulsions and then cultured without the emulsions for 24 h or 72 h in the presence of the various challenging agents. The supernatant was collected, and the secreted markers quantitated with flow cytometry or an ELISA (ELISA). Gene expression of inflammatory markers was evaluated only in the PBMCs and HCE-2 cells stimulated with LPS. The in vitro protein kinase C (PKC) binding assay for IC50 determination was performed using standard procedures. Results: The CE-CKC emulsions decreased inflammatory gene expression in LPS-stimulated PBMCs (IFN-γ, IL-17A, CXCL-9, and TNFα) and LPS-stimulated HCE-2 cells (THBS1 and CCL2). Both CE-CKC emulsions inhibited the secretion of IL-17 (from anti-CD3/anti-CD28-stimulated TCD4), TNFα, IFN-γ, and IL-2 (from anti-CD3-/anti-CD28-stimulated PBMCs), and IL-6 and IL-8 (from LPS-stimulated HCE-2). The in vitro PKC binding assay revealed that CKC, the cationic agent, is a specific PKCα inhibitor. In addition, tyloxapol, another excipient, showed some anti-inflammatory activity on IL-6 and IL-8 in the LPS-stimulated HCE-2 cells. Conclusions: This study indicates that the CE-CKC emulsions are able to directly modulate the secretion and expression of proinflammatory cytokines and chemokines. The results also suggest that CKC and tyloxapol are pharmacol. active excipients with potentially beneficial effects in vivo. These data shed new light on the efficacy observed on the DED signs of these CE-CKC emulsions in clin. trials. This study involved multiple reactions and reactants, such as N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride (cas: 122-18-9Product Details of 122-18-9).

Cation Effect of Chloride Salting Agents on Transition Metal Ion Hydration and Solvent Extraction by the Basic Extractant Methyltrioctylammonium Chloride was written by Lommelen, Rayco;Onghena, Bieke;Binnemans, Koen. And the article was included in Inorganic Chemistry in 2020.SDS of cas: 5137-55-3 The following contents are mentioned in the article:

The addition of a nonextractable salt has an important influence on the solvent extraction of metal ions, but the underlying principles are not completely understood yet. However, relating solute hydration mechanisms to solvent extraction equilibrium is key to understanding the mechanism of solvent extraction of metal ions as a whole. We have studied the speciation of Co(II), Zn(II), and Cu(II) in aqueous solutions containing different chloride salts to understand their extraction to the basic extractant methyltrioctylammonium chloride (TOMAC). This includes the first speciation profile of Zn(II) in chloride media with the three Zn(II) species [Zn(H₂O)₆]²⁺, [ZnCl₃H₂O]^–, and [ZnCl₄]^2-. The observed differences in extraction efficiency for a given transition metal ion can be explained by transition metal ion hydration due to ion-solvent interactions, rather than by ion-solute interactions or by differences in speciation. Chloride salting agents bearing a cation with a larger hydration Gibbs free energy reduce the free water content more, resulting in a lower hydration for the transition metal ion. This destabilizes the transition metal chloro complex in the aqueous phase and increases the extraction efficiency. Salting agents with di- and trivalent cations reduce the transition metal chloro complex hydration less than expected, resulting in a lower extraction efficiency. The cations of these salting agents have a very large hydration Gibbs free energy, but the overall hydration of these salts is reduced due to significant salt ion pair formation. The general order of salting-out strength for the extraction of metal ions from chloride salt solutions is Cs⁺ < Rb⁺ < NH₄⁺ ≈ K⁺ < Al³⁺ ≈ Mg²⁺ ≈ Ca²⁺ ≈ Na⁺ < Li⁺. These findings can help in predicting the optimal conditions for metal separation by solvent extraction and also contribute to a broader understanding of the effects of dissolved salts on solutes. Addition of a nonextractable salt influences the stability and solvent extraction efficiency of metal complexes. Cations of different chloride salts reduce the solution free water content as a function of their increasing hydration energy and decreasing tendency for ion pair formation with chloride anions. These ion-solvent interactions reduce the hydration of metal complexes, increasing their distribution ratios. These effects influence aqueous transition metal complexes more than direct ion-solute interactions and changes in complex speciation.

High performance of ionic-liquid-based materials to remove insecticides was written by Francisco, Rafael;Almeida, Catarina;Sousa, Ana C. A.;Neves, Marcia C.;Freire, Mara G.. And the article was included in International Journal of Molecular Sciences in 2022.SDS of cas: 5137-55-3 The following contents are mentioned in the article:

Neonicotinoids are systemic insecticides commonly used for pest control in agriculture and veterinary applications. Due to their widespread use, neonicotinoid insecticides (neonics) are found in different environmental compartments, including water, soils, and biota, in which their high toxicity towards non-target organisms is a matter of great concern. Given their widespread use and high toxicity, the development of strategies to remove neonics, while avoiding further environmental contamination is of high priority. In this work, ionic-liquid-based materials, comprising silica modified with tetraalkylammonium cations and the chloride anion, were explored as alternative adsorbent materials to remove four neonics insecticides, namely imidacloprid, acetamiprid, thiacloprid, and thiamethoxam, from aqueous media. These materials or supported ionic liquids (SILs) were first synthesized and chem. characterized and further applied in adsorption studies. It was found that the equilibrium concentration of the adsorbate in the solid phase decreases with the decrease in the SIL cation alkyl chain length, reinforcing the relevance of hydrophobic interactions between ionic liquids (ILs) and insecticides. The best-identified SIL for the adsorption of the studied insecticides corresponds to silica modified with propyltrioctylammonium chloride ([Si][N3888]Cl). The saturation of SILs was reached in 5 min or less, showing their fast adsorption rate towards all insecticides, in contrast with activated carbon (benchmark) that requires 40 to 60 min. The best fitting of the exptl. kinetic data was achieved with the Pseudo Second-Order model, meaning that the adsorption process is controlled at the solid-liquid interface. On the other hand, the best fitting of the exptl. isotherm data is given by the Freundlich isotherm model, revealing that multiple layers of insecticides onto the SIL surface may occur. The continuous removal efficiency of the best SIL ([Si][N3888]Cl) by solid-phase extraction was finally appraised, with the maximum adsorption capacity decreasing in the following sequence: imidacloprid > thiacloprid > thiamethoxam > acetamiprid. Based on real reported values, under ideal conditions, 1 g of [Si][N3888]Cl is able to treat at least 106 m3 of wastewater and water from wetland contaminated with the studied neonics. In summary, the enhanced adsorption capacity of SILs for a broad diversity of neonics was demonstrated, reinforcing the usefulness of these materials for their removal from aqueous matrixes and thus contributing to preventing their introduction into the ecosystems and reducing their detrimental effects in the environment and human health.

Discovery of boronic acid-based potent activators of tumor pyruvate kinase M2 and development of gastroretentive nanoformulation for oral dosing was written by Patle, Rajkumar;Shinde, Shital;Patel, Sagarkumar;Maheshwari, Rahul;Jariyal, Heena;Srivastava, Akshay;Chauhan, Neelam;Globisch, Christoph;Jain, Alok;Tekade, Rakesh K.;Shard, Amit.

Several studies have established that cancer cells explicitly over-express the less active isoform of pyruvate kinase M2 (PKM2) is critical for tumorigenesis. The activation of PKM2 towards tetramer formation may increase affinity towards phosphoenolpyruvate (PEP) and avoidance of the Warburg effect. Herein, we describe the design, synthesis, and development of boronic acid-based mols. as activators of PKM2. The designed mols. were inspired by existing anticancer scaffolds and several fragments were assembled in the derivatives I [R¹ = H, F, methoxy, Cl; R² = H; R³ = N(CH₃)₂, Phenyl; R⁴= H] were synthesized using a multi-step synthetic strategy in 55-70% yields, starting from cheap and readily available materials. The compounds were selectively cytotoxic to kill the cancerous cells at 80 nM, while they were non-toxic to the normal cells. The kinetic studies established the compounds as novel activators of PKM2 and I [R¹ = Cl; R² = H; R³ = N(CH₃)₂; R⁴= H] emerged as the most potent derivative I [R¹ = Cl; R² = H; R³ = N(CH₃)₂; R⁴= H] was further evaluated using various in silico tools to understand the mol. mechanism of tetramer formation. Docking studies revealed that I [R¹ = Cl; R² = H; R³ = N(CH₃)₂; R⁴= H] binds to the PKM2 dimer at the dimeric interface. Further to ascertain the binding site and mechanism of action, rigorous MD (mol. dynamics) simulations were undertaken, which led to the conclusion that I [R¹ = Cl; R² = H; R³ = N(CH₃)₂; R⁴= H] stabilizes the center of the dimeric interface that possibly promotes tetramer formation. We further planned to make a tablet of the developed mol. for oral delivery, but it was seriously impeded owing to poor aqueous solubility of I [R¹ = Cl; R² = H; R³ = N(CH₃)₂; R⁴= H]. To improve aqueous solubility and retain I [R¹ = Cl; R² = H; R³ = N(CH₃)₂; R⁴= H] at the lower gastrointestinal tract, thiolated chitosan-based nanoparticles (TCNPs) were prepared and further developed as tablet dosage form to retain anticancer potency in the excised goat colon. Our findings may provide a valuable pharmacol. mechanism for understanding metabolic underpinnings that may aid in the clin. development of new anticancer agents targeting PKM2.

Ratiometric Flapping Force Probe That Works in Polymer Gels was written by Yamakado, Takuya;Saito, Shohei. And the article was included in Journal of the American Chemical Society in 2022.Recommanded Product: 5137-55-3 The following contents are mentioned in the article:

Polymer gels have recently attracted attention for their application in flexible devices, where mech. robust gels are required. While there are many strategies to produce tough gels by suppressing nanoscale stress concentration on specific polymer chains, it is still challenging to directly verify the toughening mechanism at the mol. level. To solve this problem, the use of the flapping mol. force probe (FLAP) is promising because it can evaluate the nanoscale forces transmitted in the polymer chain network by ratiometric anal. of a stress-dependent dual fluorescence. A flexible conformational change of FLAP enables real-time and reversible responses to the nanoscale forces at the low force threshold, which is suitable for quantifying the percentage of the stressed polymer chains before structural damage. However, the previously reported FLAP only showed a negligible response in solvated environments because undesirable spontaneous planarization occurs in the excited state, even without mech. force. Here, we have developed a new ratiometric force probe that functions in common organogels. Replacement of the anthraceneimide units in the flapping wings with pyreneimide units largely suppresses the excited-state planarization, leading to the force probe function under wet conditions. The FLAP-doped polyurethane organogel reversibly shows a dual-fluorescence response under sub-MPa compression. Moreover, the structurally modified FLAP is also advantageous in the wide dynamic range of its fluorescence response in solvent-free elastomers, enabling clearer ratiometric fluorescence imaging of the mol.-level stress concentration during crack growth in a stretched polyurethane film: (a) Synthesis of a segmented polyurethane elastomer (SPU1) that is chem. doped with FLAP1-OH as a force probe. (b) Stress-strain curves of different SPUs. (c) FL spectral change of SPU1 during the tensile test. Photographs of the specimen under UV light are shown on the right side. (d) Absorption spectral change of SPU1 during the tensile test. (e) FL intensity ratio plotted against nominal stress in the tensile test.

The extraction of metals from waste printed circuit boards (WPCBs) with ionic liquids (ILs), Deep Eutectic Solvents (DESs) and organophosphorous-based acid (Cyanex 272) has been presented. The study was undertaken to assess the effectiveness of the application of the new leaching liquids, and the new method of extraction of metals from the leachate and the solid phase with or without the leaching process. Solvent extraction from the liquid leachate phase has been studied in detail with popular ILs, such as tetraoctylphosphonium bromide, [P_8,8,8,8][Br] and tributyltetradecylphosphonium chloride, [P_4,4,4,14][Cl] using Aqueous Biphasic Systems (ABS) method. Trihexyltetradecylphosphonium bis(2,4,4-trimethylpentyl) phosphinate, [P6,6,6,14][Cyanex272], ([P_6,6,6,14][BTMPP]), trihexyltetradecylphosphonium thiocyanate, [P6,6,6,14][SCN], methyltrioctylammonium chloride (Aliquat 336), as well as bis(2,4,4-trimethylpentyl)phosphinic acid (Cyanex 272) were also used in the extraction of metals from the leachate. Two DESs (1) {choline chloride + lactic acid, 1:2} and (2) {choline chloride + malonic acid, 1:1} were used in the extraction of metals from the solid phase. The extraction behavior of metals with DESs was compared with that performed with three new bi-functional ILs: didecyldimethylammonium salicylate, [N10,10,1,1][Sal], didecyldimethylammonium bis(2-ethylhexyl) phosphate, [N10,10,1,1][D2EHPA], and didecyldimethylammonium bis(2,4,4-trimethylpentyl) phosphinate, [N10,10,1,1][Cyanex272]. The [P_6,6,6,14][Cyanex272]/toluene and (Cyanex 272 + di-Et phosphite ester) mixtures exhibited a high extraction efficiency of about 50-90% for different metal ions from the leachate. High extraction efficiency of about 90-100 wt% with the ABS method using the mixture {[P_8,8,8,8][Br], or [P_4,4,4,14][Cl] + NaCl + H₂O₂ + post-leaching liquid phase} was obtained. The DES 2 revealed the efficiency of copper extraction, E_Cu = 15.8 wt% and silver, E_Ag = 20.1 wt% at pH = 5 from the solid phase after the thermal pre-treatment and acid leaching. The solid phase extraction efficiency after thermal pre-treatment only was (E_Cu = 9.6 wt% and E_Ag = 14.2 wt%). The use of new bi-functional ILs did not improve the efficiency of the extraction of metal ions from the solid phase. Process factors such as solvent concentration, extraction additives, stripping and leaching methods, temperature, pH and liquid/solid as well as organic/water ratios were under control. For all the systems, the selectivity and distribution ratios were described. The proposed extraction processes can represent alternative paths in new technologies for recovering metals from electronic secondary waste. This study involved multiple reactions and reactants, such as N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3Application In Synthesis of N-Methyl-N,N-dioctyloctan-1-aminium chloride).

The presence of alk. phosphatases has been observed in several species and has been known to play a crucial role in various biol. functions. Higher expressions of alk. phosphatase have been found in several multifactorial disorders and cancer patients, which has led it to be an interesting target for drug discovery. A strong structural similarity exists between intestinal alk. phosphatases (IAPs) and tissue-nonspecific alk. phosphatases (TNAPs), which has led to the discovery of only a few selective inhibitors. Therefore, a series of 22 derivatives of 6-(chloromethyl)-4-(4-hydroxyphenyl)-2-oxo-1,2,3,4-tetrahydropyrimidine-5-carboxylate and Et 6-(chloromethyl)-4-(2-hydroxyphenyl)-2-oxo-1,2,3,4-tetrahydropyrimidine-5-carboxylate were synthesized to evaluate the anticancer potential of these compounds against breast cancer. The compounds were characterized through spectral and elemental analyses. The inhibitory effect of dihydropyrimidinone derivatives on alk. phosphatases was evaluated using the calf alk. phosphatase assay. The antioxidant activity of these compounds was performed to study the radical scavenging effect. In silico mol. docking and mol. dynamic simulations were performed to elucidate the binding mode of active compounds Moreover, the two-dimensional qual.-structure-activity relationship (2D-QSAR) was performed to study the structural requirements for enzyme inhibition. The calf alk. phosphatase inhibitory assay revealed significant inhibition of the enzyme by compound I with IC₅₀ 1.27μM at 0.1 mM concentration as compared to standard KH₂PO₄ having IC₅₀ 2.80μM. Several compounds also showed very good inhibition with IC₅₀ values of 2.502, 2.943, and 2.132μM, resp., at the same concentration The antioxidant assay revealed efficient radical scavenging activity of three compounds at 100μg/mL with IC₅₀ values of 0.48, 0.61, and 0.75μg/mL, resp. The mol. docking and simulation studies revealed efficient binding of active compounds in the active binding site of the target enzyme. The final QSAR equation revealed good predictivity and statistical validation having R² = 0.958 and Q² = 0.903, resp., for the generated model. The compound I showed the highest inhibitory activity with stable binding modes acting as a future lead for identifying alk. phosphatase inhibitors. The mol. simulations suggested the stable binding of this compound, and the QSAR studies revealed the importance of autocorrelated descriptors in the inhibition of alk. phosphatase. The investigated compounds may serve as potential pharmacophores for potent and selective alk. phosphatase inhibitors. We intend to further investigate the biol. activities of these compounds as alk. phosphatase inhibitors.

A series of new antipyrine incorporated thiazole derivatives I (R = CHO, {2-[(5Z)-5-[(4-chlorophenyl)methylidene]-4-oxo-4,5-dihydro-1,3-thiazol-2-yl]hydrazin-1-ylidene}methyl, [2-(4-oxo-4,5-dihydro-1,3-thiazol-2-yl)hydrazin-1-ylidene]methyl, [2-(5-acetyl-4-methyl-1,3-thiazol-2-yl)hydrazin-1-ylidene]methyl, etc.) having phenoxyacetamide moiety as a link bridge was synthesized. The synthetic strategy involves condensation of the precursor N-(4-antipyrinyl)-2-(4-formylphenoxy)acetamide with thiosemicarbazide followed by heterocyclization of the produced thiosemicarbazone with various α-halogenated carbonyl compounds (namely; 4-chlorophenacyl bromide, Et bromoacetate, 3-chloroacetylacetone and Et 4-chloroacetoacetate). Moreover, the quantum chem. calculations at DFT/B3LYP level were used to determine the HOMO-LUMO energies and Fukui’s indexes toward nucleophilic, electrophilic and radical attacks. The investigated compounds were arranged due to HOMO-LUMO energy gap as following I ((2-[(5Z)-5-[(4-chlorophenyl)methylidene]-4-oxo-4,5-dihydro-1,3-thiazol-2-yl]hydrazin-1-ylidene)methyl[2-(4-oxo-4,5-dihydro-1,3-thiazol-2-yl)hydrazin-1-ylidene]methyl[2-(5-acetyl-4-methyl-4,5-dihydro-1,3-thiazol-2-yl)hydrazin-1-ylidene]methyl[(carbamothioylamino)imino]methyl(CHO){2-[4-(4-chlorophenyl)-1,3-thiazol-2-yl]hydrazin-1-ylidene}methyl({2-[4-(2-ethoxy-2-oxoethyl)-1,3-thiazol-2-yl]hydrazin-1-ylidene}methyl). The synthesized antipyrinyl-thiazole hybrids were screened to evaluate their antibacterial and antifungal efficacies. Using Chloramphenicol as reference material, the synthesized antipyrinyl-thiazole hybrids were revealed a remarkable activity against S. aureus than B. subtilis, as example for Gram’s pos. strains. The antipyrine-thiazole compounds I (R = [2-(5-acetyl-4-methyl-1,3-thiazol-2-yl)hydrazin-1-ylidene]methy, 4-(4-chlorophenyl)-1,3-thiazol-2-yl, (5Z)-5-[(4-chlorophenyl)methylidene]-4-oxo-4,5-dihydro-1,3-thiazol-2-yl and Et 2-(4-methyl-1,3-thiazol-5-yl)acetate) exhibited significant MIC values. However, the antipyrine-thiazole hybrid displayed reputable activities against Gram’s neg. strains S. typhimurium and E. coli, resp., in comparison with Cephalothin. Likewise, the compounds I (R = {[2-(5-acetyl-4-methyl-1,3-thiazol-2-yl)hydrazin-1-ylidene]methyl, 2-[4-(2-ethoxy-2-oxoethyl)-1,3-thiazol-2-yl]hydrazin-1-ylidene}methyl) were demonstrated respectable antifungal efficacy toward C. albicans in contrast to cycloheximide grade. The theor. mol. docking studies were applied to simulate reactivity of the synthesized antipyrine-thiazole hybrids against contrasting binding sites for both of Staphylococcus aureus ”Homo sapiens” (pdb: 3HUN) protein and E.coli ”Homo sapiens” (PDB: 2EXB) protein. The theor. and practical antibacterial and antifungal activities result in this work designated a proper agreement. This study involved multiple reactions and reactants, such as Ethyl 4-chloro-3-oxobutanoate (cas: 638-07-3Recommanded Product: Ethyl 4-chloro-3-oxobutanoate).

Synthesis, anticancer and antimicrobial evaluation of new benzofuran based derivatives: PI3K inhibition, quorum sensing and molecular modeling study was written by El-Khouly, Omar A.;Henen, Morkos A.;El-Sayed, Magda A.-A.;Shabaan, Mona I.;El-Messery, Shahenda M.. And the article was included in Bioorganic & Medicinal Chemistry in 2021.Reference of 638-07-3 The following contents are mentioned in the article:

A new series of benzofuran derivatives , e.g., I [R = CH₂CO₂Et, Ph, 4-MeC₆H₄, etc.] and II [R¹ = Ph, 4-ClC₆H₄, 3-MeC₆H₄, etc.], were designed and synthesized. All synthesized compounds were evaluated for anticancer activity against hepatocellular carcinoma (HePG2), mammary gland breast cancer (MCF-7), epithelioid carcinoma cervix cancer (Hela) and human prostate cancer (PC3). Compounds I [R = Me, CH₂CO₂Et, Ph] showed the highest activity toward the four cell lines with an IC₅₀ range of 8.49-16.72μM, 6.55-13.14μM and 4-8.99μM resp. in comparison to DOX (4.17-8.87μM). Phosphatidylinositol-3-kinases (PI3K) inhibition was evaluated against the most active anticancer compounds I [R = Me, CH₂CO₂Et, Ph]. Compounds I [R = Me, CH₂CO₂Et, Ph] showed good inhibitory activity against PI3Kα with IC₅₀ values 4.1, 7.8, and 20.5μM, resp. in comparison to 6.18μM for the reference compound LY294002. In addition, activity of compounds I [R = CH₂CO₂Et, Ph] on cell cycle arrest and induction of apoptosis in different phases of MCF-7 cells were assessed and detected pre-G1 apoptosis and cell growth arrest at G2/M. Also, both extrinsic and intrinsic apoptosis in MCF-7 cells induced by compounds I [R = CH₂CO₂Et, Ph]. Mol. docking, binding affinity surface mapping and contact preference of the synthesized compounds I [R = Me, CH₂CO₂Et, Ph] against PI3K were estimated and studied computationally using mol. operating environment software (MOE) and showed good interaction with essential residues for inhibition Val851. In addition, antimicrobial activity was evaluated against gram pos. isolates as Staphylococcus aureus and Bacillus cereus, gram neg. isolate as Escherichia coli, Pseudomonas aeruginosa and antifungal potential against Candida albicans. Compound II [R¹ = 3-MeC₆H₄] showed outstanding anti Gram-pos. activity with MIC values 8 and 256μg/mL in Staphylococcus aureus and Bacillus cereus resp. Also, compounds II [R¹ = 4-MeC₆H₄, 3-MeC₆H₄, 4-NO₂C₆H₄] and 2-(4-methoxyphenyl)-2-oxoethyl (E)-2-(1-(benzofuran-2-yl)ethylidene)hydrazine-1-carbodithioate showed good anti Gram-neg. activity with MIC value 512μg/mL for all compounds In addition, the state-of-art quorum sensing (QS) inhibiting effects were detected using Chromobacterium violaceum and compounds I [R = Me, CH₂CO₂Et, 4-MeC₆H₄, benzofuran-2-yl] and (E)-1-(benzofuran-2-yl)-3-(dimethylamino)prop-2-en-1-one showed good QS inhibition (3, 3, 5, 2, and 7 mm). This study involved multiple reactions and reactants, such as Ethyl 4-chloro-3-oxobutanoate (cas: 638-07-3Reference of 638-07-3).

Ethyl 4-chloro-3-oxobutanoate (cas: 638-07-3) belongs to organic chlorides. An organic chloride is an organic compound containing at least one covalently bonded atom of chlorine. Their wide structural variety and divergent chemical properties lead to a broad range of names and applications.While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available. Alkyl chlorides readily undergo attack by nucleophiles.Reference of 638-07-3
