This study involved multiple reactions and reactants, such as 3-Hydroxy-5-(hydroxymethyl)-2-methylisonicotinaldehyde hydrochloride (cas: 65-22-5Application of 65-22-5).

3-Hydroxy-5-(hydroxymethyl)-2-methylisonicotinaldehyde hydrochloride (cas: 65-22-5) belongs to alcohols. Because alcohols are easily synthesized and easily transformed into other compounds, they serve as important intermediates in organic synthesis. Converting an alcohol to an alkene requires removal of the hydroxyl group and a hydrogen atom on the neighbouring carbon atom. Dehydrations are most commonly carried out by warming the alcohol in the presence of a strong dehydrating acid, such as concentrated sulfuric acid.Application of 65-22-5

Utilization of pyridoxal acetal salts as water-triggered, slow-release pro-fragrances was written by Weeks, Kellie L.;Rutkowski, Kyle R.;Morales Loyola, Arnold A.;Boyce, Gregory R.. And the article was included in New Journal of Chemistry in 2018.Category: alcohols-buliding-blocks The following contents are mentioned in the article:

The synthesis of pyridoxal acetal salts and the controlled-release of the alcs. in the presence of neutral pH water is described. The rate of release was monitored by ¹H NMR and was found to be dependent on the concentration of water in the sample. The acetal salts are stable in the absence of moisture and show promise as a vitamin-based pro-fragrance delivery system. This study involved multiple reactions and reactants, such as 3-Hydroxy-5-(hydroxymethyl)-2-methylisonicotinaldehyde hydrochloride (cas: 65-22-5Category: alcohols-buliding-blocks).

3-Hydroxy-5-(hydroxymethyl)-2-methylisonicotinaldehyde hydrochloride (cas: 65-22-5) belongs to alcohols. Alcohols are weak acids. The most acidic simple alcohols (methanol and ethanol) are about as acidic as water, and most other alcohols are somewhat less acidic. Alcohols may be oxidized to give ketones, aldehydes, and carboxylic acids. These functional groups are useful for further reactions. Oxidation of organic compounds generally increases the number of bonds from carbon to oxygen (or another electronegative element, such as a halogen), and it may decrease the number of bonds to hydrogen.Category: alcohols-buliding-blocks
