Applications Pyridine Hydrochloride is the hydrochloride salt of pyridine, a basic six-membered heterocyclic ring. Pyridine is a base structure present in many biologically active compounds like the vitamins niacin and pyridoxal. Pyridine is used in dehalogenation reactions and can be used as a base in condensation reactions. References Egyed, J. et al.: Bull. Soc. Chim. Fra., 11, 3014 (1973); Li, Y. et al.: Wuli HUa.

Pyridine hydrochloride

Pyridine hydrochloride is a white crystalline solid. It has high values for affinity to the CB2 receptor and can be used for the treatment of metabolic disorders, such as diabetes. Pyridine hydrochloride can be synthesized in two ways: by hydrogenation of pyridine with hydrochloric acid or by reacting pyridine with hydrogen fluoride. This compound also has an effect on locomotor activity and increases glutamate levels in the brain, which may contribute to its therapeutic effects. Pyridine hydrochloride is also used as a fluorescent derivative in analytical methods that measure nucleotide levels, such as the phosphorimager technique.
