Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) that require functionalized piperidine moieties. Its protected amine group allows for selective reactions in multi-step organic syntheses, making it valuable in drug discovery and development. Commonly employed in the preparation of central nervous system agents, receptor agonists, and enzyme inhibitors where a substituted piperidine scaffold is needed. The tert-butyloxycarbonyl (Boc) protection enables mild deprotection conditions, preserving sensitive functional groups in complex molecules.
