Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) for anti-inflammatory and antimicrobial agents. Its halogenated aromatic structure makes it valuable in medicinal chemistry for modifying molecular reactivity and binding affinity. Commonly employed in cross-coupling reactions such as Suzuki or Heck reactions to build complex organic molecules. Also utilized in agrochemical synthesis for creating herbicides and pesticides due to its stability and reactivity profile. Its carboxylic acid functionality allows for easy derivatization into esters, amides, or other functional groups to tailor properties for specific applications.
