Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system (CNS) agents. Its structure supports the creation of bioactive molecules with selectivity for neurological targets. Commonly employed in medicinal chemistry for optimizing drug candidates due to the stability and steric properties provided by the tert-butoxycarbonyl (Boc) protecting group. Facilitates the construction of complex piperidine-based compounds found in active pharmaceutical ingredients (APIs).
