It differs from pyridoxamine by the substituent at the '4' position. It is often used as 'pyridoxine hydrochloride'. 3, 4-Pyridinedimethanol, 5-hydroxy-6-methyl-, hydrochloride 5-Hydroxy-6-methyl-3,4-pyridinedicarbinol hydrochloride 5-Hydroxy-6-methyl-3,4-pyridinedimethanol hydrochloride Adermin hydrochloride Aderoxin Becilan Gravidox Pyridoxin hydrochloride Pyridoxine chloride Pyridoxine hydrochloride, USAN Pyridoxine hydrogen chloride Pyridoxol hydrochloride C8H12ClNO3 205.639 205.050570962 4,5-bis(hydroxymethyl)-2-methylpyridin-3-ol hydrochloride pyridoxine hydrochloride 58-56-0 Cl.CC1=C(O)C(CO)=C(CO)C=N1 InChI=1S/C8H11NO3.ClH/c1-5-8(12)7(4-11)6(3-10)2-9-5;/h2,10-12H,3-4H2,1H3;1H ZUFQODAHGAHPFQ-UHFFFAOYSA-N belongs to the class of organic compounds known as pyridoxines. These are pyridoxal derivatives in which the carbaldehyde group at position 2 of the pyridoxal moiety is replaced by a hydroxymethyl group.
