English synonyms: ai3-01240; Azine; cp32; NCI-C55301; Piridina; Pirydyna; Pyridin (1. Modifikation); pyridine carboxylic acid, 2 - (4, 5-dihydro-4-methyl) - 5-oxo-1h-imidazol-2-yl) - 5-methyl
CAS: 110-86-1
Molecular formula: C5H5N
Molecular weight: 79.1
EINECS: 203-809-9
Melting point -42 degree C
Boiling point 96-98 degree C (lit.)
Density 0.983 g/mL at 20 degree C

Application: Some of the pyridine derivatives are important drugs and some are important components of vitamins or enzymes. For example, the amide of pyridine-3-carboxylic acid, nicotinamide, forms an important dinucleotide with adenine (see purine), ribose, and phosphoric acid in coenzyme I. Isoniazid, a derivative of pyridine, is an oral antituberculous drug. 2-methyl5 - vinyl pyridine is an important raw material for synthetic rubber. Pyridine can be obtained from natural coal tar, and can also be made from acetaldehyde and ammonia. In addition to being used as a solvent, pyridine can also be used in industry as a denaturant, dyeing aids, and starting materials for the synthesis of a range of products, including drugs, disinfectants, dyes, food seasonings, adhesives, and so on.
