Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) for anti-inflammatory and central nervous system drugs. Its structure allows for selective functionalization, making it valuable in constructing complex organic molecules. Commonly employed in cross-coupling reactions such as Suzuki-Miyaura and Heck reactions to form biaryl systems found in bioactive compounds. Also utilized in agrochemical research for designing herbicides and fungicides due to its halogenated aromatic framework that enhances biological activity. Its carboxylic acid group enables easy derivatization into esters, amides, or acid chlorides for further synthetic applications.
