Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of active ingredients requiring substituted aromatic structures. Its functional groups—cyano, nitro, and carboxylic acid—allow for diverse chemical transformations, making it valuable in constructing complex molecules. Commonly employed in the preparation of dyes, pigments, and specialty organic compounds where electron-withdrawing groups are needed to modulate reactivity or physical properties. Also utilized in research settings for derivatization reactions and building blocks in heterocyclic chemistry.
