Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of active pharmaceutical ingredients (APIs) where fluorinated and chlorinated aromatic compounds enhance metabolic stability and binding affinity. Commonly employed in the development of anti-inflammatory and central nervous system agents. Also utilized in agrochemical synthesis for creating herbicides and fungicides due to its ability to improve bioavailability and environmental persistence. Its carboxylic acid functionality allows for easy derivatization into esters, amides, or salts, facilitating integration into larger molecular structures.
