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 halogenated aromatic structure makes it valuable in medicinal chemistry for facilitating cross-coupling reactions, such as Suzuki or Heck reactions, enabling the construction of complex molecules. Also employed in agrochemical synthesis for creating herbicides and fungicides due to its ability to enhance bioactivity and stability in target compounds. Its carboxylic acid functionality allows for easy derivatization into esters, amides, or salts, broadening its utility in drug design and optimization.
