General description
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。
Application
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。

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.
