Used as a chiral building block in the synthesis of biologically active compounds, particularly in pharmaceuticals targeting central nervous system disorders. Its sulfonamide group enhances metabolic stability, while the trifluoromethyl group improves lipophilicity and bioavailability. Commonly employed in the development of selective enzyme inhibitors and receptor modulators due to its rigid structure and stereochemical purity. Also utilized in asymmetric synthesis to introduce chirality in drug candidates.
