Used as a chiral intermediate in the synthesis of biologically active compounds, particularly in pharmaceuticals targeting central nervous system disorders. Its structure supports the development of selective receptor modulators due to the stereochemistry and electron-withdrawing trifluoromethyl group. Commonly employed in the preparation of serotonin and dopamine receptor ligands. Also utilized in asymmetric synthesis to introduce chirality in drug candidates. Its stability and functional group compatibility make it suitable for multi-step synthetic routes in medicinal chemistry.
