Pyridoxine Hydrochloride (syn: Vitamin B6) is the hydrochloride salt of Pyridoxine. It is a pyridine derivative and is involved in a variety of enzymatic transformations and plays a role as an antioxidant in biological systems. Pyridoxine was isolated and crystallized in 1938 by Samuel Lepkovsky. It can be converted in animals into the enzymatically active form pyridoxal-5-phosphate. Pyridoxal-5-phosphate is used in metabolic utilization and transformation of amino acids and is a cofactor in the synthesis of neurotransmitters and sphingolipids.
Pyridoxine Hydrochloride is soluble in water and DMSO but insoluble in ethanol.
