一般描述
四甲基氯化铵(TMAC)在结构上类似于烷基三甲基铵盐。TMAC的氧化产生甲醛和三甲胺。由于它不溶于有机介质，因此被认为是大多数反应的不良相转移催化剂。但是，它非常适合作为相转移催化剂，与碱金属氟化物一起氟化氯苯甲醛，从而产生1,2,2,2-四氟乙基二氟甲基醚。
应用
TMAC可用于离子交换程序中，以显示pH的增加，以使用Knoevenagel缩合模型了解催化剂[CTA]Si-MCM-41的化学行为。

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.
