Used as a key chiral intermediate in the synthesis of biologically active pharmaceuticals, particularly in the development of enzyme inhibitors and receptor modulators. Its trifluoroethylamine structure enhances metabolic stability and binding selectivity, making it valuable in medicinal chemistry for optimizing drug candidates. Commonly employed in the preparation of small-molecule therapeutics targeting neurological and metabolic disorders. The nitrile group allows for further functionalization, enabling diverse derivatization for structure-activity relationship studies.
