Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of active pharmaceutical ingredients (APIs) that require functionalized piperidine moieties. Its protected amine and activated hydroxyl group allow selective reactions in multi-step organic syntheses. Commonly employed in the preparation of kinase inhibitors, antiviral agents, and central nervous system modulators. Suitable for use in coupling reactions and nucleophilic substitutions due to the tosylate leaving group. The tert-butyl carbamate (Boc) protection ensures amine stability during reaction sequences, enabling deprotection under mild acidic conditions when needed.
