The kinetics and mechanism of condensation of pyridoxal hydrochloride with L-α-asparagine, L-α- and D-α-aspartic acids are analyzed via UV spectroscopy and polarimetry. It is found that L-α-asparagine containing α-NH2 and γ-NH2 groups interacts with pyridoxal via the γ-NH2 group, forming Schiff bases that are resistant to chem. transformations. Rearrangement produces Schiff bases that form the cyclic structure from the amino acid moiety. L-α- and D-α-aspartic acids interacting with pyridoxal via α-NH2 groups create Schiff bases that form quinoid structures after elimination of α-hydrogen or CO2. Their subsequent hydrolysis results in pyridoxamine, α-ketoacids, and aldehyde acids, resp. Schemes of the condensation mechanisms of L-α-asparagine, L-α-, D-α-aspartic acids with pyridoxal hydrochloride are proposed. This study involved multiple reactions and reactants, such as 3-Hydroxy-5-(hydroxymethyl)-2-methylisonicotinaldehyde hydrochloride (cas: 65-22-5SDS of cas: 65-22-5).
3-Hydroxy-5-(hydroxymethyl)-2-methylisonicotinaldehyde hydrochloride (cas: 65-22-5) belongs to alcohols. Under appropriate conditions, inorganic acids also react with alcohols to form esters. To form these esters, a wide variety of specialized reagents and conditions can be used. Secondary alcohols are easily oxidized without breaking carbon-carbon bonds only as far as the ketone stage. No further oxidation is seen except under very stringent conditions.SDS of cas: 65-22-5
