Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of active ingredients requiring substituted aromatic structures. Its nitro and carboxylic acid functional groups allow for further chemical modifications, such as reduction to amine derivatives or coupling reactions. Commonly employed in research settings for constructing complex organic molecules, including dyes and specialty polymers. Also finds use in the preparation of ligands for catalytic processes due to its ability to form stable complexes with metal ions.
