Use Of Pyridine
Sep 30, 2017

Some of the many derivatives of pyridine are important drugs, some of which are important components of vitamins or enzymes. For example, pyridine-carboxylic acid amide (ie, nicotinamide), in Coenzyme I with adenine (see purine), ribose and phosphoric acid form an important two nucleotides. Pyridine derivative isoniazid is an oral anti-TB drug. 2-methyl-vinyl pyridine is an important raw material for synthetic rubber. Pyridine can be obtained from natural coal tar or made from acetaldehyde and ammonia. In addition to being solvent, pyridine can also be used industrially as a denaturing agent, an aid dye, and a starter for a range of products, including pharmaceuticals, disinfectants, dyes, food seasonings, adhesives, explosives, etc.
