Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in medicinal chemistry due to its halogenated aromatic structure, which enhances binding selectivity and metabolic stability in drug candidates. Also employed in the preparation of agrochemicals and bioactive molecules where fluorinated and chlorinated heterocycles improve efficacy and environmental persistence. Its carboxylic acid functionality allows for easy derivatization into amides, esters, and other functional groups critical in structure-activity relationship studies.
