P-Nitrobenzoic acid

CAS: 62-23-7

P-Nitrobenzoic acid is a nitro compound that is used as an intermediate in the synthesis of various pharmaceuticals. It is also used in wastewater treatment to remove protocatechuic acid, which is produced during the oxidation of phenols by peroxidase. P-Nitrobenzoic acid can be synthesized by reacting sodium nitrite with p-hydroxybenzoic acid. The structure of this compound was determined through a series of experiments, and it was found that it has two nitrogen atoms that are incorporated into the benzene ring. This compound reacts with aziridine in an exothermic reaction mechanism to form an unstable five membered ring. This reaction proceeds through a series of steps and eventually forms p-nitrobenzoic acid.
