Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) requiring stereochemical control. Its protected amine group allows for selective reactions in multi-step organic syntheses. Commonly employed in the production of drugs targeting central nervous system disorders, including antidepressants and antipsychotics. Also utilized in the preparation of enzyme inhibitors and receptor modulators due to its rigid piperidine scaffold and defined stereochemistry. Widely applied in medicinal chemistry for structure-activity relationship (SAR) studies.
