Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of active pharmaceutical ingredients (APIs) requiring protected functional groups. Its structure allows for selective modification in multi-step organic syntheses, especially in the preparation of nitrogen-containing heterocyclic drugs. Commonly employed in medicinal chemistry for constructing peptidomimetics and CNS-targeted agents due to the piperidine backbone. The benzyloxycarbonyl (Cbz) protecting group facilitates controlled deprotection under mild conditions, making it valuable in solid-phase and solution-phase peptide coupling strategies.
