Used as an intermediate in pharmaceutical synthesis, particularly in the development of active pharmaceutical ingredients (APIs) involving piperazine derivatives. Its protected structure allows selective reactions at specific sites, making it valuable in multi-step organic synthesis. Commonly employed in the preparation of drug candidates targeting central nervous system disorders, antimicrobial agents, and receptor agonists or antagonists. The tert-butyl and methyl ester groups facilitate easy deprotection, enabling further functionalization in medicinal chemistry workflows.
