Used as an intermediate in the synthesis of biologically active compounds, particularly in pharmaceutical development. It serves as a chiral building block for drugs targeting central nervous system disorders due to the presence of the fluorinated aryl piperazine moiety, which is commonly found in serotonin receptor modulators. Its tert-butoxycarbonyl (Boc) protection allows for selective functionalization of the piperazine ring in multi-step syntheses. Commonly employed in the preparation of potential antidepressants, anxiolytics, and antipsychotic agents.
