Preparation
editIt has been prepared from 3-nitrobenzaldehyde in a sequence of nitro group reduction, diazotization of the amine, and hydrolysis.[3][4]
3-hydroxybenzyl-alcohol dehydrogenase is an NADP-dependent enzyme that produces 3-hydroxybenzaldehyde from 3-hydroxybenzyl alcohol.[5]
Biomedical properties
edit3-Hydroxybenzaldehyde exhibits vasculoprotective effects by lowering vascular smooth muscle cell proliferation and endothelial cells inflammation.[6] 3-Hydroxybenzaldehyde is used in the synthesis of monastrol.[7][8]
