4-Nitrobenzoic acid is an organic compound with the formula C6H4(NO2)CO2H. It is a precursor to 4-nitrobenzoyl chloride, the precursor to the anestheic Procaine and folic acid. It is also a precursor to 4-aminobenzoic acid. [6]
4-Nitrobenzoic acid is prepared by oxidation of 4-nitrotoluene using oxygen or nitric acid as oxidants. Alternatively, it has been prepared by nitration of polystyrene followed by oxidation of the alkyl substituent. This method proceeds with improved para/ortho selectivity owing to the steric protection of the ortho positions by the polymer backbone.
