Used as a key intermediate in the synthesis of biologically active compounds, particularly in pharmaceuticals targeting central nervous system disorders. Its structure supports the development of selective enzyme inhibitors and receptor modulators. The presence of the trifluoromethyl group enhances metabolic stability and lipophilicity, making it valuable in drug design for improving bioavailability and binding affinity. Commonly employed in medicinal chemistry for optimizing lead compounds in the development of antidepressants, antipsychotics, and cognitive enhancers.
