4-Pyridinealdoxime Chemical Properties,Uses,Production

Chemical Properties

white very fine crystalline powder

Uses

An intermediate for bis(hydroxyiminomethylpyridinium)butenes as reactivators of chlorpyrifos-inhibited acetylcholinesterase.

Uses

It is employed as an intermediate for bis(hydroxyiminomethylpyridinium)butenes and as reactivators of chlorpyrifos-inhibited acetylcholinesterase. It is also used in the chromatographic separation and NMR characterization of the isomers of 1,1-Methylenebis{4-[(hydroxyimino)methyl]pyridinium) dichloride.

Purification Methods

Crystallise the oxime from water. [Beilstein E-isomer 21 III/IV 3533, 21/7 V 355.]
