2-Picoline
Natural oily liquid with a pyridine odor. Spontaneous combustion point 537.8℃. Easily soluble in water, can be miscible with alcohol, ether. Risk of combustion and explosion in contact with open flame, high heat or oxidant. Decomposition by heat releases toxic nitrogen oxide fumes. In case of high heat, the pressure inside the container increases, and there is a risk of cracking and explosion.
1. Used as solvent and chromatographic analysis reagent, also used in organic synthesis industry
2.2-methylpyridine is an intermediate of the plant growth regulator pyridinol.
3. It is used to prepare 2-vinylpyridine, nitrogen-based synergist (N-Serve), long-acting sulfanilamide, anti-silicogenic drug, livestock deworming drug, poultry drug, organophosphorus antidote, local anesthetic, laxative, additive of film sensitizer, dye intermediate and rubber accelerator, etc.
4. Used as raw materials for synthetic medicine, dyes, resins, chemical fertilizer synergists, herbicides, livestock repellents, rubber accelerators, dye intermediates, etc
5. Used for the synthesis of drugs, dyes, rubber and other chemicals, and also used as solvents and experimental reagents
6. Test cobalt, cyanate and iron. Organic synthesis.
