일반 설명
Tetramethylammonium chloride (TMAC) is structurally similar to alkyltrimethylammonium salts. Oxidation of TMAC yields formaldehyde and trimethlamine. It is considered as poor phase-transfer catalyst for most reactions as it is insoluble in organic media. However, it is highly suitable as phase-transfer catalyst for fluorination of chlorobenzaldehydes along with alkali metal fluorides which yield 1,2,2,2-tetrafluoroethyldifluoromethyl ether.
애플리케이션
TMAC may be used in ion-exchange procedures to show the increase of pH in understanding the chemical behaviour of catalyst [CTA]Si-MCM-41 using Knoevenagel condensation model.

The Fbw7 tumor suppressor targets a broad network of proteins for ubiquitylation. Here we show critical functions for Fbw7 dimerization in regulating the specificity and robustness of degradation. Dimerization enables Fbw7 to target substrates through concerted binding to two suboptimal

A simple and low-cost colorimetric assay utilizing ferrofluidic nanoparticulate probes (FNPs) and a ligase for single-nucleotide polymorphism genotyping is described. Excellent sensitivity and selectivity were accomplished through the engagement of the FNPs and a ligase chain reaction.
