• 2-Mercaptoethylpyridine is a most unusual organic compound, possessing a sulfhydryl group in addition t o the pyridine ring. T h e presence of the sulfhydryl group makes 2-Mercaptoethylpyridine a most reactive and versatile pyridine compound. 2-Mercaptoethylpyridine is available in 9 5 % minimum purity, with a minimum freezing point of —27.4°C. A few of the suggested uses are: as a polymerization modifier in synthetic rubber; as a vulcanization accelerator; as a plasticizer; as an insecticide and fungicide; as a raw material in the synthesis of dyestuffs and pharmaceuticals; as an intermediate in the preparation of sulfides, thioesters and metal salts; as a starting material for the synthesis of pickling inhibitors, flotation reagents, emulsifying and wetting agents and as a solvent.
