Used as an intermediate in the synthesis of biologically active compounds, particularly in pharmaceuticals targeting central nervous system disorders. Its structure supports the development of fluorinated analogs with enhanced metabolic stability and binding affinity. Commonly employed in medicinal chemistry for optimizing lead compounds due to the electron-withdrawing properties and steric protection provided by the trifluorophenyl and tert-butoxycarbonyl groups. Also utilized in the preparation of protease inhibitors and receptor modulators where cyclopropane rings and fluorine substitution improve pharmacokinetic profiles.
