| | 4-Pyridinealdoxime Usage And Synthesis |
| Chemical Properties | white very fine crystalline powder | | 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. | | Uses | An intermediate for bis(hydroxyiminomethylpyridinium)butenes as reactivators of chlorpyrifos-inhibited acetylcholinesterase. | | Purification Methods | Crystallise the oxime from water.
