Robust polyamide-PTFE hollow fibre membranes for harsh organic solvent nanofiltration was written by Francis, Verona Nithya;Chong, Jeng Yi;Yang, Guoying;Che, Lei;Wang, Rong. And the article was included in Chemical Engineering Journal (Amsterdam, Netherlands) in 2023.Category: chlorides-buliding-blocks This article mentions the following:

Polymeric membranes have been extensively studied for organic solvent nanofiltration (OSN) but many fail to show sufficient chem. resistance in strong solvents like DMF (DMF) and DMSO (DMSO). This study focuses on harnessing the outstanding chem. resistance of polytetrafluoroethylene (PTFE), to develop polyamide-PTFE thin film composite (TFC) membranes that are resistant to such aprotic solvents. A defect-free polyamide thin film layer was successfully synthesized on the microfiltration PTFE hollow fiber substrates, overcoming challenges such as large and uneven pore size, and hydrophobicity of the PTFE substrates. A simple polydopamine (PDA) coating was carried out to improve the substrate’s hydrophilicity prior to the polyamide synthesis via interfacial polymerization (IP). Polyethyleneimine (PEI) and trimesoyl chloride (TMC) were used as the monomers and a two-time IP method was employed to obtain a defect-free polyamide coating. The synthesized membranes showed high acetonitrile (ACN) and DMF permeabilities of 7.94 and 3.70 lm^-2h^-1bar^-1, resp., with acid fuchsin (585 Da) rejections of > 90%. The mol. weight cut-off (MWCO) of the membranes could be further reduced to ∼300 Da by the addition of piperazine (PIP) monomers. The membranes also showed excellent stability and performance in a 72-h OSN test performed in DMF indicating their great potential in effective mol. separation in harsh solvents. This study demonstrates how a simple modification and coating technique can transform com. available microfiltration PTFE hollow fibers into durable and high value OSN membranes. In the experiment, the researchers used many compounds, for example, Trimesoylchloride (cas: 4422-95-1Category: chlorides-buliding-blocks).

Three simple titrimetric methods were developed to determine I-Br numbers of some edible oils, such as coconut, gingelly, peanut, mustard, olive, palm olein, and sunflower, by using 3 N-chloroimides.

Synthesis and properties of a mitochondrial peripheral benzodiazepine receptor conjugate was written by El Alaoui, Abdessamad;Schmidt, Frederic;Sarr, Marianne;Decaudin, Didier;Florent, Jean-Claude;Johannes, Ludger. And the article was included in ChemMedChem in 2008.Name: tert-Butyl (4-chlorophenyl)carbamate This article mentions the following:

Peripheral benzodiazepine receptors are potential targets for cancer therapeutics through the use of specific ligands such as the pro-apoptotic benzodiazepine RO5-4864. However, the poor water solubility of this compound has been a limitation to its application in vivo. Herein we describe an efficient synthesis for the conjugation, via a cleavable linker arm, of RO5-4864 to a novel tumor-delivery tool, the B-subunit of Shiga toxin (STxB). The conjugate is water soluble and specifically targets cancer cells that overexpress the glycolipid Gb3, the cellular Shiga toxin receptor that is found on several human tumors. After internalization via retrograde transport, the prodrug is cleaved inside cells to release the active principle. Delivery by STxB therefore increases in cytotoxic activity of RO5-4864 and its tumor specificity. In the experiment, the researchers used many compounds, for example, tert-Butyl (4-chlorophenyl)carbamate (cas: 18437-66-6Name: tert-Butyl (4-chlorophenyl)carbamate).

And the article was included in Chemistry – A European Journal in 2020.SDS of cas: 202925-07-3 This article mentions the following:

A mild and transition-metal-free approach for the nucleophilic aromatic substitution (S_NAr) of unactivated fluoroarenes with primary aliphatic amines to form aromatic amines was reported. This reaction is facilitated by the formation of cationic fluoroarene radical intermediates in the presence of an acridinium-based organic photocatalyst under blue-light irradiation Various electron-rich and electron-neutral fluoroarenes are competent electrophiles for this transformation. A wide range of primary aliphatic amines, including amino acid esters, dipeptides and linear and branched amines are suitable nucleophiles. The synthetic utility of this protocol is demonstrated by the late-stage functionalization of several complex drug mols. In the experiment, the researchers used many compounds, for example, 2-Chloro-1-fluoro-4-methoxybenzene (cas: 202925-07-3SDS of cas: 202925-07-3).

And the article was included in Journal of Medicinal Chemistry in 2008.Quality Control of 2-Chloro-6-fluorophenylacetonitrile This article mentions the following:

A series of dihydro-alkylthio-benzyl-oxopyrimidines (S-DABOs) bearing a 2-aryl-2-oxoethylsulfanyl chain at pyrimidine C2, an alkyl group at C5, and a 2,6-dichloro-, 2-chloro-6-fluoro-, and 2,6-difluoro-benzyl substitution at C6 (oxophenethyl-S-DABOs, 6-8) is here described. The new compounds showed low micromolar to low nanomolar (in one case subnanomolar) inhibitory activity against wt HIV-1. Against clin. relevant HIV-1 mutants (K103N, Y181C, and Y188L) as well as in enzyme (wt and K103N, Y181I, and L100I mutated RTs) assays, compounds carrying an ethyl/iso-Pr group at C5 and a 2,6-dichloro-/2-chloro-6-fluoro-benzyl moiety at C6 were the most potent derivatives, also characterized by low fold resistance ratio. Interestingly, the structure-activity relationship (SAR) data drawn from this DABO series are more related to HEPT than to DABO derivatives These findings were at least in part rationalized by the description of a fair superimposition between the 6-8 and TNK-651 (a HEPT analog) binding modes in both WT and Y181C RTs.

Enhancement of micro-filtration performance for biologically-treated leachate from municipal solid waste by ozonation in a micro bubble reactor was written by Cheng, Wen;Quan, Xuejun;Huang, Xiaoxue;Cheng, Chen;Yang, Lu;Cheng, Zhiliang. And the article was included in Separation and Purification Technology in 2018.Formula: C18H37Cl This article mentions the following:

The degradation of recalcitrant organic compounds in biol.-treated municipal solid waste leachate (MSW) was investigated using pre-ozonation in a micro bubble reactor. The effects of operating parameters such as reactor pressure, liquid phase temperature, inlet ozone concentration and ozone flow rate on micro filtration (MF) performance were studied systematically. It is demonstrated that the MF was obviously enhanced with ozonation time before 45 min and increasing inlet ozone concentration, as well as increasing ozone flow rate. Addnl., the reactor pressure and liquid phase temperature have no obvious effects on improving MF performance. And the mechanism for the enhancement of MF performance was explored through anal. of the colloids present in the leachate by SEM and organic compounds by GC/MS. The micro flocculation effect and the reduction of hydrocarbon and heterocycle compounds in the leachate by ozonation treatment were responsible for improving the MF performance. In the experiment, the researchers used many compounds, for example, 1-Chlorooctadecane (cas: 3386-33-2Formula: C18H37Cl).
