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. Grignard and organolithium reagents are powerful tools for organic synthesis, and the most common products of their reactions are alcohols.COA of Formula: C8H10ClNO3

Pyridoxal azomethine salts was written by Bagautdinova, R. H.;Kibardina, L. K.;Pudovik, E. M.;Burilov, A. R.;Pudovik, M. A.. And the article was included in Russian Journal of General Chemistry in 2019.COA of Formula: C8H10ClNO3 The following contents are mentioned in the article:

The reactions of 4-methylpiperazin-1-amine, 2-amino- and 4-aminomethylpiperidines with pyridoxal afforded the corresponding azomethines. Their reactions with organic and inorganic acids lead to the formation of salt derivatives of pyridoxal azomethines. This study involved multiple reactions and reactants, such as 3-Hydroxy-5-(hydroxymethyl)-2-methylisonicotinaldehyde hydrochloride (cas: 65-22-5COA of Formula: C8H10ClNO3).
