Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of active pharmaceutical ingredients (APIs) that require a piperazine backbone with functionalized side chains. Its structure allows for selective modifications, making it valuable in creating drug candidates targeting central nervous system disorders, antipsychotics, and antidepressants. The tert-butyl carbamate (Boc) group provides protection during synthesis, enabling controlled reactions in multi-step organic transformations. Commonly employed in medicinal chemistry for building complex molecules with improved bioavailability and receptor selectivity.
