Pyridoxine Hydrochloride (Vitamin B6) CAS 58-56-0
Pyridoxine hydrochloride, the common stable form of vitamin B6 (CAS 58-56-0), is a white, odorless crystalline powder that dissolves freely in water. Food, supplement and feed makers use it to add vitamin B6 to fortified foods, tablets, drink powders, animal premixes and personal care products. The hydrochloride form is stable in dry air and easy to dose, but should be kept away from light. UATChem supplies food, pharmacopoeia, feed and cosmetic grades in foil bags, 25 kg cartons and fibre drums. Keep packs sealed, dry and dark; send grade, quantity and destination for COA, TDS and SDS.

What Pyridoxine Hydrochloride Is
Pyridoxine hydrochloride (C₈H₁₁NO₃·HCl) is the standard commercial form of vitamin B6, a white crystalline powder freely soluble in water. It is stable in dry air but loses quality in sunlight, so keep stock sealed, dry and dark. Buyers choose food grade for fortification, pharmacopoeia material for medicine, or feed and cosmetic grade. UATChem supplies all four, with assay on the COA.
