Used in pharmaceutical research as a key intermediate for developing bioactive molecules, particularly in the synthesis of enzyme inhibitors and receptor modulators. Shows potential in the development of central nervous system agents due to its structural affinity for neurotransmitter transporters. Also employed in the design of protease inhibitors, leveraging the trifluoromethyl group to enhance metabolic stability and binding selectivity. Commonly utilized in structure-activity relationship (SAR) studies to optimize potency and pharmacokinetic properties in drug candidates.
