Application
 

Pyridine is used as a solvent in paint andrubber industries; as an intermediate in dyesand pharmaceuticals; for denaturing alcohol;and as a reagent for cyanide analysis. Itoccurs in coal tar.

Pyridine and derivatives of pyridine occur widely in nature as components of alkaloids, vitamins, and coenzymes. These compounds are of continuing interest to theoretical physical, organic, and biochemistry and to industrial chemistry. Pyridine and derivatives have many uses, e.g., herbicides and pesticides, pharmaceuticals, feed supplements, solvents and reagents, and chemicals for the polymer and textile industries.
