As polar, basic, low-reactive solvent, precursor, and reagent, pyridine finds wide range of applications in pharmaceuticals, agrochemicals and in the manufacture of dyes and rubber. Further it is used in the textile industry to improve network capacity of cotton. Pyridine finds applications in specialty chemical reagents like Cornforth reagent (pyridinium dichromate, PDC), pyridinium chlorochromate (PCC), the Collins reagent (complex of chromium(VI) oxide with pyridine) and the Sarret reagent (complex of chromium(VI) oxide with pyridine). Pyridine is a widely used ligand in coordination chemistry. Pyridine-base adducts like pyridine-borane (C5H5NBH3) and pyridine-sulfur trioxide (C5H5NSO3) are widely used owing to their superior characteristics in their reactivity and solubility characteristics.
