Used as an intermediate in pharmaceutical synthesis, particularly in the development of bioactive molecules targeting central nervous system disorders. Its morpholine ring and trifluoromethylphenyl group contribute to enhanced metabolic stability and binding affinity in drug candidates. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to its favorable physicochemical properties and ability to modulate lipophilicity and solubility. Also utilized in the preparation of protease inhibitors and receptor antagonists in research settings.
