Used primarily as an intermediate in organic synthesis, especially in the production of pharmaceuticals and agrochemicals. Its nitro and carboxylic acid functional groups allow for further chemical modifications, such as reduction of the nitro group to an amine or conversion of the acid to esters and amides. Commonly employed in the development of active ingredients in herbicides and anti-inflammatory drugs. Also utilized in research settings for constructing complex aromatic molecules due to its substituted benzene ring structure.
