    en.wikipedia.org/wiki/Pralidoxime

    Pralidoxime (2-pyridine aldoxime methyl chloride) or 2-PAM, usually as the chloride or iodide salts, belongs to a family of compounds called oximes that bind to organophosphate-inactivated acetylcholinesterase. [1] It is used to treat organophosphate poisoning [2] in conjunction with atropine and either diazepam or midazolam. It is a white solid.

  8. Nicotinonitrile - Wikipedia

    en.wikipedia.org/wiki/Nicotinonitrile

    A colorless solid, it is produced by ammoxidation of 3-methylpyridine: [2] H 3 CC 5 H 4 N + NH 3 + 1.5 O 2 → NCC 5 H 4 N + 3 H 2 O. Nicotinonitrile is a precursor to the vitamin niacin. [3] Nitrilase-catalyzed hydrolysis of 3-cyanopyridine by means of immobilized Rhodococcus rhodochrous J1 [2] strains leads in quantitative yield to ...

  9. Picoline - Wikipedia

    en.wikipedia.org/wiki/Picoline

    3-Methylpyridine degrades more slowly than the other two isomers, likely due to the impact of resonance in the heterocyclic ring. Like most simple pyridine derivatives, the picolines contain more nitrogen than is needed for growth of microorganisms, and excess nitrogen is generally excreted to the environment as ammonium during the degradation ...
