4-Dimethylaminopyridine

　　Usage:

　　Catalytic acylation reaction: It is a super-strong nucleophilic acylation catalyst that can significantly catalyze the acylation of highly sterically hindered and low-reactivity alcohols and amines. Its activity is approximately \(10^4\) - \(10^6\) times that of pyridine. It can be used in the production of active pharmaceutical ingredients such as acetyl(propionyl)spiramycin, artemisinin succinate, and statin lipid-lowering drugs.

　　Other reactions: It can also be used to catalyze silylation reactions of alcohols, lactonization reactions, etc., and can be used as a phase transfer catalyst for interfacial reactions. In pesticide production, it has obvious catalytic activity for the synthesis of allethrin and the synthesis of carbamates from isocyanates.
