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. Tertiary alcohols cannot be oxidized at all without breaking carbon-carbon bonds, whereas primary alcohols can be oxidized to aldehydes or further oxidized to carboxylic acids.Recommanded Product: 65-22-5

An air and water insensitive visible light induced hydrophosphinylation of unactivated alkenes is reported. A small amount of a simple and cheap compound, salicylaldehyde, is used as a photosensitizer. The reaction is carried out in a basic aqueous solution which enables the deprotonated salicylaldehyde to show visible light absorption. This study involved multiple reactions and reactants, such as 3-Hydroxy-5-(hydroxymethyl)-2-methylisonicotinaldehyde hydrochloride (cas: 65-22-5Recommanded Product: 65-22-5).
