Widely used in pharmaceutical research as a key intermediate in the synthesis of biologically active compounds, particularly in the development of enzyme inhibitors and receptor modulators. Its unique trifluoroethyl group enhances binding affinity and metabolic stability, making it valuable in drug discovery. Commonly employed in the creation of potential therapeutic agents targeting neurological disorders, cancer, and inflammatory diseases. Also utilized in asymmetric synthesis to produce chiral molecules with high enantiomeric purity.
