Used primarily in pharmaceutical research as a key intermediate in the synthesis of bioactive molecules. Its sulfonamide structure makes it valuable for developing compounds with potential antipsychotic, antidepressant, or anti-inflammatory activity. The electron-withdrawing trifluoromethyl groups enhance metabolic stability and influence binding affinity in drug candidates. It is also employed in the preparation of receptor ligands, particularly in central nervous system (CNS) drug discovery programs. Due to its hydrochloride salt form, it exhibits improved solubility and handling properties in aqueous reaction systems.
