3D-FDA54769 - 3-hydroxy-4-methoxy-5-nitrobenzaldehyde | 80547-69-9

5-Nitrovanillin is a white crystalline solid with a molecular formula of C8H7NO2. It reacts with nucleophilic compounds, such as ammonia, in the presence of heat to produce a molecule containing an oxygen atom and two nitro groups. 5-Nitrovanillin has been found to undergo demethylation when heated in the presence of hydroxylamine. Reaction products include protocatechuic acid, nitromethane, and 5-nitrobenzoic acid. This compound can be identified by its characteristic nmr spectrum that includes a hydroxyl group and a hydrogen bond between the nitrogen atom and the hydroxyl group. The chemical ionization mass spectrometer can also be used to identify 5-nitrovanillin.
