Benzoic acid, the simplest aromatic carboxylic acid containing carboxyl group bonded directly to benzene ring, is a white, crystalline organic compound melting at

4-Nitrobenzoic acid is produced commercially by the oxidation of 4-nitrotoluene with molecular oxygen. Oxidation with 15% nitric acid at 175 °C produces the acid in 88.5% yield. /Another/ method involves the nitration and subsequent oxidation of polystyrene.

pNB and pNOBA are intermediates only; when dissolved in PBS containing glutathione, pNB was converted to pNBA and pNBOH, while pNOBA gave pABA (De Vries et al., 1994).

4-Nitrobenzoic acid (p-nitrobenzoic acid) is a carboxylic acid derivative. It participates in the biosynthesis of the antibiotic aureothin. Infrared Fourier transform spectroscopic studies suggest that the molecules of 4-nitrobenzoic acid gets adsorbed on the surfaces of fine silver powder as carboxylate. Application In this manner the p-nitrobenzoic acid is obtained in the form of flake-like, pale yellow crystals.
