The application of deep eutectic solvents (DESs) in biotechnol. processes has gained an outstanding relevance, as they can be used as greener media to obtain higher productivities and selectivities. In the present contribution, an eutectic mixture composed of choline chloride (ChCl): glycerol (1 : 2 mol/mol) has been used as a reaction medium in combination with Tris-SO₄ 50 mM buffer pH 7.5, applied to the alc. dehydrogenase (ADH)-catalyzed reduction of various carbonyl precursors of chiral halohydrins. These alcs. are key intermediates of biol. active compounds, and hence they are of industrial interest. In the presence of up to 50% volume/volume of DES, these biotransformations were achieved up to 300-400 mM of the α-halogenated ketone substrate, getting access to the final compounds with excellent conversions (usually >90%) and enantiomeric excess (ee >99%). Among the different ADHs tested, two stereocomplementary enzymes (Lactobacillus brevis ADH and Rhodococcus ruber ADH) afforded the best results, so both alc. enantiomers could be obtained in all the studied examples. Selected bioredns. were scaled up to 250 mg and 1 g, demonstrating the potential that DESs can offer as media in redox processes for substrates with low solubility in water. This study involved multiple reactions and reactants, such as Ethyl 4-chloro-3-oxobutanoate (cas: 638-07-3Computed Properties of C6H9ClO3).

Ethyl 4-chloro-3-oxobutanoate (cas: 638-07-3) belongs to organic chlorides. Chlorination modifies the physical properties of hydrocarbons in several ways. These compounds are typically denser than water due to the higher atomic weight of chlorine versus hydrogen. The haloform reaction, using chlorine and sodium hydroxide, is also able to generate alkyl halides from methyl ketones, and related compounds. Chloroform was formerly produced thus.Computed Properties of C6H9ClO3

And the article was included in Environmental Technology.Related Products of 5137-55-3 The following contents are mentioned in the article:

This work aims to removing anionic food dyes, Acid Red18 (E124) and Quinoline Yellow WS (E104), from their aqueous solutions The Emulsion Liquid Membrane (ELM) technique was used. ELM consists of diluent (kerosene), nonionic surfactant (0.5 weight% Triton X-45), Aliquat 336 as an extractant. Sulfuric acid (H₂SO₄) solution was used as an internal aqueous phase. The key parameters impacting the stability of liquid membrane and the efficiency of dye removal were investigated; Almost 98% of E124 at 50 mg/L are successfully extracted under optimum conditions. The extraction of a mixture of the two dyes at equal concentrations (25 mg/L) was conducted and their extraction showed more than 95% of efficiency. The exptl. results of dye mixture (E124, E104) extraction were expressed by the following three quantities: The concentration of Triton X-45, the concentration of Aliquat 336, and the internal phase concentration of H₂SO₄, represented on three dimensional plots using the Box-Behnken design and the response surface methodol. For each of the parameters, the values of which were determined by exptl. design, these results were subjected to empirical smoothing. The values, thus calculated, are consistent with the measurements. This study involved multiple reactions and reactants, such as N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3Related Products of 5137-55-3).

N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3) belongs to organic chlorides. Chlorination modifies the physical properties of hydrocarbons in several ways. These compounds are typically denser than water due to the higher atomic weight of chlorine versus hydrogen. Organochlorine compounds are lipophylic, meaning they are more soluble in fat than in water. This gives them a high tenancy to accumulate in the food chain (biomagnification).Related Products of 5137-55-3

Electrochemical properties of a lithium-impregnated metal foam anode (LIMFA FeCrAl) for molten salt thermal batteries was written by Choi, Yusong;Ahn, Tae-Young;Ha, Sang-Hyeon;Lee, Jae-In;Cho, Jang-Hyeon. And the article was included in Scientific Reports in 2022.Synthetic Route of ClLi The following contents are mentioned in the article:

Although numerous cathode materials with excellent properties have been developed for use in molten salt thermal batteries, similar progress is yet to be made with anode materials. Herein, a high-performance lithium-impregnated metal foam anode (LIMFA) is fabricated by impregnating molten lithium into a gold-coated iron-chrome-aluminum (FeCrAl) foam at 400°C. A test cell employing the LIMFA FeCrAl anode exhibited a specific capacity of 2627 As g^-1. For comparison, a cell with a conventional Li(Si) anode was also discharged, demonstrating a specific capacity of 982 As g^-1. This significant improvement in performance can be attributed to the large amount (18 wt%) of lithium incorporated into the FeCrAl foam and the ability of the FeCrAl foam to absorb and immobilize molten lithium without adopting a cup system. For thermal batteries without a cup, the LIMFA FeCrAl provides the highest-reported specific capacity and a flat discharge voltage curve of molten lithium. After cell discharge, the FeCrAl foam exhibited no lithium leakage, surface damage, or structural collapse. Given these advantageous properties, in addition to its high specific capacity, LIMFA FeCrAl is expected to aid the development of thermal batteries with enhanced performance. This study involved multiple reactions and reactants, such as Lithium chloride (cas: 7447-41-8Synthetic Route of ClLi).

Lithium chloride (cas: 7447-41-8) 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. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. However, the extent of chlorination is difficult to control.Synthetic Route of ClLi

And the article was included in Environmental Science & Technology in 2021.Recommanded Product: 122-18-9 The following contents are mentioned in the article:

Quaternary ammonium compounds (QACs) are commonly used in a variety of consumer, pharmaceutical, and medical products. In this study, bioaccumulation potentials of 18 QACs with alkyl chain lengths of C8-C18 were determined in the in vitro-in vivo extrapolation (IVIVE) model using the results of human hepatic metabolism and serum protein binding experiments The slowest in vivo clearance rates were estimated for C12-QACs, suggesting that these compounds may preferentially build up in blood. The bioaccumulation of QACs was further confirmed by the anal. of human blood (sera) samples (n = 222). Fifteen out of the 18 targeted QACs were detected in blood with the ΣQAC concentrations reaching up to 68.6 ng/mL. The blood samples were collected during two distinct time periods: before the outbreak of the COVID-19 pandemic (2019; n = 111) and during the pandemic (2020, n = 111). The ΣQAC concentrations were significantly higher in samples collected during the pandemic (median 6.04 ng/mL) than in those collected before (median 3.41 ng/mL). This is the first comprehensive study on the bioaccumulation and biomonitoring of the three major QAC groups and our results provide valuable information for future epidemiol., toxicol., and risk assessment studies targeting these chems.

The efficient screening of solvents for CO₂ capture requires a reliable and robust equation of state to characterize and compare their thermophys. behavior for the desired application. In this work, the potentiality of 14 ionic liquids (ILs) and 7 deep eutectic solvents (DESs) for CO₂ capture was examined using soft-SAFT as a modeling tool for the screening of these solvents based on key process indicators, namely, cyclic working capacity, enthalpy of desorption, and CO₂ diffusion coefficient Once the models were assessed vs. exptl. data, soft-SAFT was used as a predictive tool to calculate the thermophys. properties needed for evaluating their performance. Results demonstrate that under the same operating conditions, ILs have a far superior performance than DESs primarily in terms of amount of CO₂ captured, being at least two-folds more than that captured using DESs. The screening tool revealed that among all the examined solvents and conditions, [C₄ py][NTf₂] is the most promising solvent for phys. CO₂ capture. The collection of the acquired results confirms the reliability of the soft-SAFT EoS as an attractive and valuable screening tool for CO₂ capture and process modeling.

Deuterated Clopidogrel Analogues as a New Generation of Antiplatelet Agents was written by Zhu, Yaoqiu;Zhou, Jiang;Jiao, Bo. And the article was included in ACS Medicinal Chemistry Letters in 2013.Recommanded Product: (S)-Methyl 2-amino-2-(2-chlorophenyl)acetate The following contents are mentioned in the article:

Clopidogrel (CPG) is an antithrombotic prodrug that needs hepatic cytochrome P 450 (CYP) enzymes for its bioactivation. The clin. effects of CPG have been associated with high intersubject variability and a certain level of resistance. Recently, comprehensive biotransformation studies of CPG support that the observed clin. uncertainty stems from the low bioactivation efficiency, which is attributed to extensive attritional metabolism (e.g., hydrolysis of the Me ester functionality and oxidation of the piperidine moiety). With the goal of potentiating the desired thiophene 2-oxidation through minimal structural modification, we have adopted the strategy of targeted metabolism shift and have designed and synthesized deuterated piperidine analogs of CPG. In vitro studies showed that the prodrug activation percentages have been significantly increased for the deuterated analogs as a result of stability enhancement of the piperidine moiety. In a pharmacol. study with a rat model, oral administration of the deuterated analogs also demonstrated higher inhibitory activity than that of CPG against ADP (ADP) induced platelet aggregation. These deuterated analogs represent a new generation of antiplatelet agents with the potential to overcome the major clin. drawbacks of CPG.

Derivatization of carbohydrates with aminooxy agents to form oximes can be used for qual. and quant. anal. of carbohydrates; however, the formation of isomeric products limits its application. A new reductive oxyamination procedure developed for the anal. of monosaccharides with a novel fluorescent O-substituted aminooxy reagent, 4-((aminooxy)methyl)-6-chloro-7-hydroxycoumarin (AOCC), is reported. In this procedure, monosaccharides undergo an oxime formation reaction with AOCC and are then readily reduced with 2-picoline-borane, followed by anal. with HPLC with fluorescence detection. Good separation of five monosaccharide derivatives was achieved within 40 min with acetonitrile-water-tetrahydrofuran as the mobile phase. The detection limits were on the order of femtomoles. The linear range was 0.2-4000 nM, with a good correlation coefficient (R ≥ 0.9985). Furthermore, the method was applied for anal. of real samples, such as bovine milk powder, without complicated and tedious sample treatment. This reductive oxyamination method circumvents the problem caused by oxime isomers and can be used for the highly sensitive and selective anal. of monosaccharides with high accuracy, providing an effective and promising method for the anal. of carbonyls with aminooxy agents.

Hybrid Nanoarchitectonics with Conductive Polymer-Coated Regenerated Cellulose Fibers for Green Electronics was written by Kwon, Goomin;Lee, Kangyun;Jeon, Youngho;Jeong, Minseok;Kim, Jeonghun;You, Jungmok.

Green electronics based on biodegradable polymers have received considerable attention as a solution to electronic waste (e-waste). Herein, we describe an efficient approach to constructing green conductive fibers, comprising poly(3,4-ethylenedioxythiophene) (PEDOT) and regenerated cellulose (RC), via a wet-spinning process and vapor-phase polymerization (VPP). Eco-friendly RC fibers were prepared as a support layer by wet spinning, and the conductive PEDOT layers were coated onto the surface of the RC fibers by the oxidation of EDOT monomers. We demonstrated that the vapor-phase-polymerized PEDOT/RC composite fibers (PEDOT/RC-VPP) exhibited approx. 17 times higher elec. conductivity (198.2 ± 7.3 S/cm), compared with that of the solution-phase-polymerized PEDOT/RC composite fibers (PEDOT/RC-SPP, 11.6 ± 0.6 S/cm). Importantly, PEDOT/RC-VPP exhibited a high tensile strength of 181 MPa, good flexibility, and long-standing elec. stability under ambient air conditions. Moreover, the obtained PEDOT/RC-VPP under 50% strain turned on a green light-emitting diode (LED), indicating the flexibility and stability of green conductive fibers. This strategy can be easily integrated into various electronic textiles for the development of next-generation wearable green electronics.
