Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) for central nervous system (CNS) drugs. It serves as a building block in the production of certain antipsychotic and antidepressant medications due to its ability to form complex heterocyclic structures. Its chloro and trifluoromethyl groups enhance reactivity and binding selectivity in drug molecules. Also employed in agrochemical synthesis for creating herbicides and plant growth regulators, where its aromatic and functional group arrangement contributes to biological activity. Commonly utilized in research laboratories for structure-activity relationship (SAR) studies in medicinal chemistry.
