clear slightly yellow liquid | [Uses]
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. | [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.] |
