4-Nitrobenzaldehyde

4-Nitrobenzaldehyde is an organic compound with the formula O2NC6H4CHO.

It is one of three isomers of nitrobenzaldehyde.

It contains a nitro group para-substituted to an aldehyde.

4-Nitrobenzaldehyde is obtained by oxidation of 4-nitrotoluene or hydrolysis of 4-nitrobenzalbromide:[3] In the laboratory, the oxidation is achieved with chromium(VI) oxide in acetic anhydride, which affords nitrobenzyldiacetate.
