This article investigates the applicability of an environmentally friendly and energy efficient deep eutectic solvents (DES) for indigotin blue dye (IBD) preconcentration prior to its quantification by a UV-Visible spectrophotometer. The adsorbent (UT-mGO) is made of Fe₃O₄, graphene oxide, urea and tetramethylammonium chloride. It was prepared via dispersing magnetic graphene oxide in a DES. The adsorbent was prepared fast and easy, without consumption of dangerous reagents. The X-ray diffraction patterns show pure structures of components. The FT-IR spectra show strong interaction between DES and mGO. In addition, a scanning electron microscope confirms that DES covered the surface of mGO homogeneously. Magnetic amount and surface property were characterized by an alternating gradient force magnetometer and Brunauer-Emmett-Teller, resp. High surface area and enough magnetic property, as well as π-π and electrostatic interactions among analyte and adsorbent propose UT-mGO as a qualified candidate to preconc. IBD. Effective parameters including pH, adsorbent amount, adsorption time, eluent and desorption time were optimized. Under the optimized conditions, the method has the following figures of merit: (a) limit of detection of 1.5 × 10^-6 g L^-1, (b) relative standard deviation (n = 7) of 3.49%, (c) preconcentration factor of 50 and (d) linearity of dynamic range of 1.0 × 10^-5 to 45 × 10^-5 g L^-1. The adsorbent is not reusable but durable in six months. Isotherm model of Langmuir and kinetic model of pseudo-second-order fitted for the system. ΔH (-13.2 × 10³ J mol^-1), ΔS (5.38 J K^-1 mol^-1) and ΔG (-3.69 × 10³ – +10.9 × 103 J mol^-1) were calculated as thermodn. parameters. The method was successfully applied for IBD preconcentration from three samples of fruit juices and three samples of jelly powders. This study involved multiple reactions and reactants, such as Tetramethylammonium chloride (cas: 75-57-0Related Products of 75-57-0).

And the article was included in Molecules in 2021.Computed Properties of C6H5ClO2 The following contents are mentioned in the article:

A series of fluorinated 7-hydroxycoumarin derivatives containing an oxime ether moiety I [R¹ = H, F; R² = Me, CF₃; R³ = H, Cl; R⁴ = H, Me, Bn, etc.] was designed, synthesized and evaluated for their antifungal activity. All the target compounds were determined by ¹H-NMR, ¹³C-NMR, FTIR and HR-MS spectra. The single-crystal structures of compounds I [R¹ = H, F R² = Me, CF₃, R³ = H, R⁴ = Et, propargyl, butyl] were further confirmed using X-ray diffraction. The preliminary bioassays showed that some of the designed compounds I displayed the promising antifungal activities against Botrytis cinerea (B. cinerea), Alternariasolani (A. solani), Gibberella zeae (G. zeae), Rhizoctorzia solani (R. solani), Colletotrichum orbiculare (C. orbiculare) and Alternaria alternata (A. alternata) were evaluated in vitro.

And the article was included in Bioorganic Chemistry in 2019.Electric Literature of C6H9ClO3 The following contents are mentioned in the article:

An operationally simple Biginelli protocol was employed for the synthesis of new C₆-carbon based aryl α-haloacrylamide-linked dihydropyrimidinone derivatives I (R = H, NHC(O)C(=CH₂)Br; R¹ = NHC(O)C(=CH₂)Br, Cl; R² = Ph, thiophen-2-yl, 4-phenylphenyl, etc.). The synthesized compounds were appraised for their in vitro antiproliferative potential against a selected panel of human cancer cell lines especially MCF-7 (human breast cancer), MDA-MB-231 (human breast cancer), HCT-116 (human colon cancer), HCT-15 (human colorectal adenocarcinoma), HT-29 (human colon adenocarcinoma) and DU145 (human prostate cancer) along with normal lung fibroblasts (HFL-1). Preferably, compounds containing α-haloacrylamide I functionality were found to exhibit most significant cytotoxicity (IC₅₀ value 0.54 ± 0.12 to 8.35 ± 0.82 μM) against the listed cancer cell lines, particularly towards breast cancer cell lines MCF-7 and MDA-MB-231 (IC₅₀ value 0.54 ± 0.12 to 3.70 ± 0.24 μM). In the seam of synthesized compounds, compound I (R = H; R¹ = NHC(O)C(=CH₂)Br; R² = 4-methylphenyl (A)) exhibited potent antiproliferative activity against breast cancer cell lines namely MCF-7 (IC₅₀ value 0.54 ± 0.12 μM) and MDA-MB-231 (IC₅₀ value 1.18 ± 0.32 μM). Further to understand the underlying apoptosis mechanisms, different staining techniques such as AO/EB, DCFDA, and DAPI staining were performed. To know the extent of apoptosis and loss of mitochondrial membrane potential in MCF-7 cell lines, annexin V-FITC/PI and JC-1 were performed. Cell cycle anal. revealed that compound (A) arrested the cells at G2/M phase in a dose-dependent manner. The compound (A) also found to exhibit significant inhibition of tubulin polymerization (IC₅₀ of 6.91 ± 0.43 μM) with microtubule destabilizing properties. Mol. docking studies also revealed that compound (A) efficiently interacted with critical catalytically active residues Ser178, Val238, and Val318 of the α/β-tubulin by a hydrogen bond.

New Surfactant Phosphine Ligands and Platinum(II) Metallosurfactants. Influence of Metal Coordination on the Critical Micelle Concentration and Aggregation Properties was written by Parera, Elisabet;Comelles, Francesc;Barnadas, Ramon;Suades, Joan. And the article was included in Langmuir in 2010.Application of 6294-17-3 The following contents are mentioned in the article:

The authors prepared the first Pt(II) metallosurfactants from a new family of linear surfactant phosphines Ph₂P(CH₂)_nSO₃Na {1 (n = 2), 2 (n = 6), and 3 (n = 10)}, which were synthesized by reaction between the halosulfonates X(CH₂)_nSO₃Na and sodium diphenylphosphide. The metallosurfactants cis-[PtCl₂L₂] (L = 1–3) were obtained after reaction between the phosphines and PtCl₂ in DMSO. All compounds were fully characterized by the usual methods {NMR (¹H, ¹³C, ³¹P, ¹⁹⁵Pt), IR, MS-ESI and HRMS}. By exploring the surfactant properties of phosphines 1–3 and their resp. Pt metallosurfactants cis-[PtCl₂L₂] (L = 1–3) through surface tension measurements, dynamic light scattering spectroscopy, and cryo-TEM microscopy, the authors were able to analyze the influence of the metal coordination on the critical micelle concentration (cmc) and the aggregation properties. The cmc values of Pt metallosurfactants were considerably lower than those obtained for the free phosphines 1–3. This behavior could be understood by an analogy between the structure of cis-[PtCl₂L₂] complexes and bolaform surfactants. The calculated values of area per mol. also showed different tendencies between 1–3 and cis-[PtCl₂L₂] complexes, which could be explained from the possible conformations of these compounds in the air-H₂O interface. The study of aggregates by dynamic light scattering spectroscopy and cryo-TEM microscopy showed the formation of spherical disperse medium size vesicles in all cases. However, substantial differences were observed between the three free phosphines (the population of micellar aggregates increased with long chain length) and also between phosphines and their resp. metallosurfactants. This study involved multiple reactions and reactants, such as 1-Bromo-6-chlorohexane (cas: 6294-17-3Application of 6294-17-3).

1-Bromo-6-chlorohexane (cas: 6294-17-3) belongs to organic chlorides. Organic chlorides can be used in production of: PVC, pesticides, chloromethane, teflon, insulators.

Reliable optoelectronic switchable device implementation by CdS nanowires conjugated bent-core liquid crystal matrix was written by Asiya, S. I.;Pal, Kaushik;El-Sayyad, Gharieb S.;Elkodous, M. Abd;Demetriades, Catherine;Kralj, Samo;Thomas, Sabu. And the article was included in Organic Electronics in 2020.Quality Control of 4-Chlororesorcinol The following contents are mentioned in the article:

Enhancing the performance of high luminescent and dielec. capable cadmium sulfide nanowire (CdS NW) is of great importance, because of their promising ability in analyzing the dimensionality and size. The tuned phys. characteristics of semiconductor CdS NWs allowed the manipulation of both electronic and optoelectronic devices at the nanoscale by dispersing a new bent core (BC) liquid crystal (LC) compound This was derived from a 4-chlororesorcinol central core unit with two terephthalate based rod-like units carrying chiral (S)-3, 7-dimethyloctyloxy (namely CPDB) terminal chains, which have been synthesized in a pure solvo-chem. process. The mesomorphic properties of the newly-prepared bent-core LC, exhibiting an enantiotropy Sm Aphase as a result of dispersing 0.005% of CdS NWs, were investigated by several spectroscopic investigations. In addition, the hydrothermal fabrication of CdS NWs with a high-yield was modified with a cationic agent, cetyltrimethyl ammonium bromide (CTAB), which was utilized as a compatibilizer for providing a better interaction with LC mols. and giving a homogeneous solution This work focused on the exptl. investigation and optimization, using a combinational view of bent-core liquid crystal (CPDB) compound dispersion which was achieved in a controllable manner. The product of the resulting composite matrix has a very outstanding and promising behavior, e.g. semiconductor nanostructures emission polarization that can be manipulated using an external bias modulation of the novel switchable device, which was found quite convincing in the recent trends of brand-new technologies. In particular, the electro-optic responses by POM of various mesophases were investigated from the view point of the CdS incorporated bent-core LC matrix formation and transitional phase variants of ON and OFF states, which were depending on the geometrical parameters of CdS NWs. Finally, the future challenges and prospects of any other nanomaterials dispersed into CPDB compound which will give rise to an increase of the mesomorphic range by preserving the mesophase type were explored in detail. This study involved multiple reactions and reactants, such as 4-Chlororesorcinol (cas: 95-88-5Quality Control of 4-Chlororesorcinol).

Mixed Solvothermal Synthesis of Tn Cluster-Based Indium and Gallium Sulfides Using Versatile Ammonia or Amine Structure-Directing Agents was written by Sun, Meng;Zhang, Shu;Wang, Kai-Yao;Wang, Juan;Cheng, Lin;Zhu, Jia-Ying;Zhao, Yi-Ming;Wang, Cheng. And the article was included in Inorganic Chemistry in 2021.COA of Formula: C4H12ClN The following contents are mentioned in the article:

Metal chalcogenide supertetrahedral Tn clusters are of current interest for their unique compositions and structures, which rely highly on the structure-directing agents. Herein, we report four novel Tn cluster-based indium and gallium sulfides, [NH(CH₃)₃]₄In₄S₁₀H₄ (1), (NH₃)₄Ga₄S₆ (2), [NH₃CH₂CH₃]₅(NH₂CH₂CH₃)₂Ga₁₁S₁₉ (3), and [NH₃CH₂CH₂OH]₆Ga₁₀S₁₈·2NH₂CH₂CH₂OH (4). All four compounds were solvothermally synthesized in mixed amine-ethanol solutions or deep eutectic solvent (DES), where ammonia/amine mols. play significant structure-directing roles in the speciation and crystal growth. (1) Being protonated, the trimethylamine and ethanolamine mols. surround the T2-[In₄S₁₀H₄]^4- clusters (for 1) and [Ga₁₀S₁₈]_n^6n- open framework (for 4), resp., compensating for the neg. charge of the inorganic moieties. (2) With the lone pair of electrons, the ammonia mols. in 2 coordinate directly to corner Ga³⁺ ions of the {Ga₄S₆} cage to give a neutral T2-(NH₃)₄Ga₄S₆ cluster. (3) For compound 3, part of the ethylamine mols. act as terminating ligands for the T1 and T3 units in the [Ga₁₁S₁₉(NH₂CH₂CH₃)₂]_n^5n- layer, while the rest act as interlamellar countercations upon protonation. Theor. studies reveal the contributions of N, C, and H to the d. of states (DOS) for 2 and 3 because of their hybrid structures that combine the ammonia/amine ligands with sulfide moieties together. This study involved multiple reactions and reactants, such as Tetramethylammonium chloride (cas: 75-57-0COA of Formula: C4H12ClN).

Layered Inorganic-Organic 3,5-Dimethylpyrazole-4-Sulfonate Films for Protection of Copper Surfaces against Corrosion was written by Al Isawi, Wisam A.;Jianrattanasawat, Sarut;Tripodianos, Eleftherios;Demadis, Konstantinos D.;Kirillov, Alexander M.;Zeller, Matthias;Mezei, Gellert. And the article was included in Crystal Growth & Design in 2021.Related Products of 75-57-0 The following contents are mentioned in the article:

A series of 11 compounds, including alkali (Li, Na, K, Rb, Cs) and alk.-earth (Mg, Ca, Sr, Ba) coordination polymers, transition-metal (Cu, Cd) complexes, and the ammonium salt of 3,5-dimethylpyrazole-4-sulfonic acid (HL), were synthesized. Single crystals of HL·H₂O, LiL(H₂O), NaL(H₂O), RbL, CsL, CaL₂(H₂O), SrL₂(H₂O), BaL₂(H₂O), CuL₂(H₂O)₃·2.3H₂O·0.5(acetone), and CdL₂(H₂O)3·2H₂O were obtained from aqueous solutions either by evaporation or acetone vapor diffusion. Characterization by single-crystal X-ray diffraction reveals that the coordination compounds of L- (except Cu) possess alternating inorganic-organic layered structures, in which L- engages in extensive charge-assisted networks of H-bonding and aromatic interactions as well as metal coordination through the pyrazole N atom and/or the sulfonate O atom. A topol. anal. and classification of underlying metal-organic or hydrogen-bonded networks uncover a number of distinct topol. nets (3,5L2, hcb, 6,6L1, 3,5C1, 3,8L28, hex, and pcu). A thermogravimetric anal. shows that HL and NH4L are stable up to 285 and 90 °C, resp., whereas the anhydrous metal compounds decompose above 200-230 °C. The pKa values of 3,5-dimethylpyrazole-4-sulfonic acid (HL) and pyrazole-4-sulfonic acid were determined by 1H NMR titrations with H₂SO₄. Copper corrosion experiments indicate that 3,5-dimethylpyrazole-4-sulfonic acid (HL) is a better anticorrosion agent than the parent pyrazole-4-sulfonic acid at pH 4, whereas the coordination polymers of L- offer weaker corrosion protection in comparison to the corresponding pyrazole-4-sulfonate complexes. The latter result is corroborated by the less compact and less robust thin films formed by metal-L compounds, as indicated by SEM/energy dispersive X-ray spectroscopy (SEM/EDS) measurements, and the weaker acidity of HL, which allows for easier protonation of the conjugate base L- in metal-L compounds This study involved multiple reactions and reactants, such as Tetramethylammonium chloride (cas: 75-57-0Related Products of 75-57-0).

Tetramethylammonium chloride (cas: 75-57-0) belongs to organic chlorides. Organic chlorides can be used in production of: PVC, pesticides, chloromethane, teflon, insulators.

Effects of Na₂SO₄ or NaCl on sonochemical degradation of phenolic compounds in an aqueous solution under Ar: Positive and negative effects induced by the presence of salts was written by Uddin, Helal Md.;Nanzai, Ben;Okitsu, Kenji. And the article was included in Ultrasonics Sonochemistry in 2016.Computed Properties of C6H5ClO2 The following contents are mentioned in the article:

Sonochem. degradation of 4-chlorophenol, phenol, catechol and resorcinol was studied under Ar at 200 kHz in the absence and presence of Na₂SO₄ or NaCl. The rates of sonochem. degradation in the absence of salts decreased in the order 4-chlorophenol > phenol > catechol > resorcinol and this order was in good agreement with the order of log P (partition coefficient) value of each phenolic compound The effects of salts on the rates of sonochem. degradation consisted of no effect or slight neg. or pos. effects. We discussed these unclear results based on two viewpoints: one was based on the changes in pseudo hydrophobicity and/or diffusion behavior of phenolic compounds and the other was based on the changes in solubility of Ar gas. The measured log P value of each phenolic compound slightly increased with increasing salt concentration In addition, the dynamic surface tension for 4-chlorophenol aqueous solution in the absence and presence of Na₂SO₄ or NaCl suggested that phenolic compounds more easily accumulated at the interface region of bubbles at higher salt concentration These results indicated that the rates of sonochem. degradation should be enhanced by the addition of salts. On the other hand, the calculated Ar gas solubility was confirmed to decrease with increasing salt concentration The yield of H₂O₂ formed in the presence of Na₂SO₄ or NaCl decreased with increasing salt concentration These results suggested that sonochem. efficiency decreased with decreasing gas amount in aqueous solution: a neg. effect of salts was observed Because neg. and pos. effects were induced simultaneously, we concluded that the effects of salts on the rates of sonochem. degradation of phenolic compounds became unclear. The products formed from sonochem. degradation of 4-chlorophenol were also characterized by HPLC anal. The formation of phenol and 4-chloro-1,3-dihydroxy benzene was confirmed and these concentrations were affected by the presence of salts.

Conducting chiral nickel(II) bis(dithiolene) complexes: structural and electron transport modulation with the charge and the number of stereogenic centers was written by Abherve, Alexandre;Mroweh, Nabil;Cauchy, Thomas;Pop, Flavia;Cui, HengBo;Kato, Reizo;Vanthuyne, Nicolas;Alemany, Pere;Canadell, Enric;Avarvari, Narcis. And the article was included in Journal of Materials Chemistry in 2021.SDS of cas: 75-57-0 The following contents are mentioned in the article:

Ni(II) bis(dithiolene) complexes can provide crystalline conducting materials either in their monoanionic or neutral forms. The use of chiral dithiolene ligands with one or two stereogenic centers, together with variation of the counterion in the anionic complexes, represents a powerful strategy to modulate the conducting properties of such mol. materials. The chiral ligands 5-methyl-5,6-dihydro-1,4-dithiin-2,3-dithiolate (me-dddt) and 5,6-dimethyl-5,6-dihydro-1,4-dithiin-2,3-dithiolate (dm-dddt) were generated from the thione precursors (1) and (2) which were structurally and chiroptically characterized. Anionic Ni(II) complexes of these two ligands with tetrabutyl-ammonium (TBA) and tetramethyl-ammonium (TMA) were prepared and structurally characterized, suggesting that it is the nature of the counterion which mostly influences the solid state organization of the complexes. Both TBA and TMA radical anion salts are Mott insulators with antiferromagnetic ground states, as suggested by spin polarized DFT band structure calculations However, the TMA salts are one order of magnitude more conducting than the TBA counterparts. The neutral materials [Ni(me-dddt)₂] and [Ni(dm-dddt)₂] are direct band gap semiconductors, as determined by DFT and extended Huckel band structure calculations, with their conductivity drastically increased up to 0.05-3.3 S cm^-1 under the highest applied pressures of 10-11 GPa. At equivalent applied pressures the dm-dddt materials are more conducting than the me-dddt ones, in agreement with the lower calculated activation energy and larger bands dispersion for the former. This trend follows the structural change when going from one to two Me substituents, since the packing and intermol. interactions are completely different between [Ni(dm-dddt)₂] and [Ni(me-dddt)₂], the packing of the latter being related to the one of the achiral parent [Ni(dddt)₂]. Subtle differences of conductivity are also observed within both series of neutral complexes between the enantiopure and racemic forms. This represents the 1st series of chiral Ni bis(dithiolene) complexes which shows modulation of the conducting properties with the number of stereogenic centers, the conductivity, measured on single crystals, strongly increasing upon applying hydrostatic pressure. This study involved multiple reactions and reactants, such as Tetramethylammonium chloride (cas: 75-57-0SDS of cas: 75-57-0).

Tetramethylammonium chloride (cas: 75-57-0) belongs to organic chlorides. Organic chlorides are compounds containing a carbon-chlorine bond, which are widely used in the oil field as a wax dissolver. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. However, the extent of chlorination is difficult to control.SDS of cas: 75-57-0
