	3-Hydroxybenzaldehyde 3-Hydroxybenzaldehyde is an organic compound with the formula . It is a colorless solid although most samples appear tan. Two other isomers of hydroxybenzaldehyde exist. Preparation It has been prepared from 3-nitrobenzaldehyde in a sequence of nitro group reduction, diazotization of the amine, and hydrolysis. 3-hydroxybenzyl-alcohol dehydrogenase is an NADP-dependent enzyme that produces 3-hydroxybenzaldehyde from 3-hydroxybenzyl alcohol. Bio-medical properties 3-Hydroxybenzaldehyde exhibits vasculoprotective effects by lowering vascular smooth muscle cell proliferation and endothelial cells inflammation. 3-Hydroxybenzaldehyde is used in the synthesis of monastrol.
