Used as a key chiral intermediate in the synthesis of pharmaceutical agents, particularly in the development of central nervous system (CNS) drugs. Its structure supports the creation of selective serotonin and dopamine modulators, making it valuable in the production of antidepressants and antipsychotics. The tert-butyloxycarbonyl (Boc) protecting group allows for controlled deprotection during multi-step syntheses, enhancing reaction specificity. Commonly employed in medicinal chemistry for building complex piperazine-based molecules with improved bioavailability and target binding affinity.
