Properties and stability
If placed in an open container, it will produce a slight odor of fatty amines. Hygroscopic.
Storage method
Should be sealed and stored in a dry place.
Synthesis method
Withβ-Chlorohydrin is used as raw material and acylated with phosgene to prepare chloroformic acid-β-Ethyl chloride: Then reacts with ammonia to form carbamic acid-β-Ethyl chloride, and finally reacts with trimethylamine to form a quaternary ammonium salt to obtain kappa Choline: Another method of preparing carbachol is to use choline chloride and urea as raw materials: when the ingredients are used, the ratio of choline chloride: urea: sodium nitrite: sulfuric acid=1：1：1.15：1.35, in60℃Response about40h, can be used as 71%The yield of carbachol was obtained.
Purpose
This product is a cholinergic drug and is also used as a parasympathetic stimulant. When used as veterinary medicine, it is used in large animals to treat acute abdominal pain in horses.
