Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system (CNS) agents. Its structure supports the creation of bioactive molecules with enhanced metabolic stability and binding affinity. Commonly employed in the preparation of novel psychotropic drugs and serotonin receptor modulators. Also utilized in research settings for structure-activity relationship (SAR) studies due to the influence of the trifluoromethyl group on lipophilicity and electron-withdrawing properties.
