What is 4-Methylpiperidine?
Chemical properties
clear slightly yellow liquid
The Uses of 4-Methylpiperidine
4-Methylpiperidine is used as a catalyst in the synthesis of stilbene derivatives as anti-malarial agents. It also serves as an anti-corrosive compound for iron.
The Uses of 4-Methylpiperidine
4-Methylpiperidine acts as a catalyst in the preparation of stilbene derivatives. It is used as an anti-corrosive compound for iron. It is also used in the synthesis of peptides to remove or deprotection of 9-fluorenylmethyloxycarbonyl (Fmoc) groups.
Purification Methods
Purify it via the hydrochloride (m 189o). It is freed from 3-methylpyridine by zone melting. The hydrobromide has m 173o(from butanone/*C6H6). [Beilstein 20 III/IV 1511, 20/4 V 116.]
