Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) that require a piperidine backbone. Its protected amine group allows for selective reactions at other functional sites, making it valuable in multi-step organic syntheses. Commonly employed in the production of central nervous system (CNS) agents, including antidepressants, antipsychotics, and analgesics. Also utilized in medicinal chemistry for constructing drug candidates during research and development due to its stability and ease of handling in coupling reactions, especially with amines to form amide bonds.
