Pyridoxal Hydrochloride (CAS 65-22-5) is the hydrochloride salt form of pyridoxal, an aldehyde derivative of vitamin B6, supplied as a white to off-white crystalline powder and used as an active B6 vitamer and precursor to pyridoxal-5-phosphate in nutraceutical and food formulations. It presents as a white to off-white crystalline powder, soluble in water and ethanol.
As an active B6 vitamer, pyridoxal hydrochloride serves as a biochemical precursor to pyridoxal-5-phosphate (PLP), the coenzyme form involved in amino acid metabolism, red blood cell formation, and neurological function. SoleChem supplies food grade and pharma grade material for industrial formulation use.
