Pyridine

Quantity : 1kg; 25kg;

As one of the important nitrogen-containing heterocyclic compounds, pyridine has been widely used in fields including photocatalysis and optoelectronic devices. In pharmaceutical chemistry, pyridine is also often used as the parent nucleus structure of drugs. At present, the deuteration reaction of pyridine is mainly carried out by metal catalysts such as Pd, Rh, Ir, Ru and Ni, and hydrogen isotope exchange (HIE) is carried out at the α-position, while HIE at other positions is rarely involved. Among the many derivatives of pyridine, some are important drugs, and some are important components of vitamins or enzymes. For example, the amide of pyridine-3-carboxylic acid (i.e., nicotinamide) forms an important dinucleotide with adenine (see purine), ribose and phosphate in coenzyme I. Isoniazid, a derivative of pyridine, is an oral anti-tuberculosis drug. 2-Methyl-5-vinylpyridine is an important raw material for synthetic rubber. In addition to being a solvent, pyridine can also be used in industry as a denaturant, dyeing aid, and a starting material for the synthesis of a series of products, including medicines, disinfectants, dyes, food seasonings, adhesives, explosives, etc.
