Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of nitroaromatic compounds with biological activity. Its functional groups—carboxylic acid, hydroxy, methoxy, and nitro—allow for selective chemical modifications, making it valuable in creating complex organic molecules. Commonly employed in research settings for designing herbicides and antimicrobial agents due to its electron-withdrawing nitro group and ability to participate in coupling reactions. Also utilized in the preparation of dyes and photoactive compounds where controlled substitution on the aromatic ring is required.
