Used in pharmaceutical research as an intermediate in the synthesis of bioactive compounds, particularly in the development of central nervous system agents and receptor modulators. Its structure supports activity in neurochemical pathways, making it valuable in the discovery of antidepressants, antipsychotics, and anxiolytic drugs. Also employed in medicinal chemistry for structure-activity relationship (SAR) studies due to the stability and polarity imparted by the trifluoromethyl and morpholine groups.
