3-Hydroxy-5-(hydroxymethyl)-2-methylisonicotinaldehyde hydrochloride (cas: 65-22-5) belongs to alcohols. Alcohols are among the most common organic compounds. They are used as sweeteners and in making perfumes, are valuable intermediates in the synthesis of other compounds, and are among the most abundantly produced organic chemicals in industry. The most common reactions of alcohols can be classified as oxidation, dehydration, substitution, esterification, and reactions of alkoxides.Product Details of 65-22-5

Chemical transformations of the condensation products of structurally different amino acids with pyridoxal as a function of Ph, solvent, and temperature was written by Pishchugin, F.

The kinetics and mechanism of chem. transformations of condensation products of structurally different amino acids with pyridoxal as a function of pH of the medium, the solvent, and temperature were studied. The Schiff bases were found to be the most stable at pH close to neutral values. In acidic media, the condensation products of α-amino acids with pyridoxal decompose to the starting components. In alk. media, the elimination of the α-hydrogen atom from the amino acid fragment and rearrangement of the Schiff base into the quinoid form occurs, the subsequent hydrolysis leading to the formation of pyridoxamine and keto acids. The condensation products of the β- and ε-amino acids with pyridoxal decompose to the starting components in acidic media but are stable in alk. media. This study involved multiple reactions and reactants, such as 3-Hydroxy-5-(hydroxymethyl)-2-methylisonicotinaldehyde hydrochloride (cas: 65-22-5Product Details of 65-22-5).
