Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) that require functionalized piperidine rings. Its protected amine group and activated hydroxyl moiety allow for selective reactions in multi-step organic syntheses. Commonly employed in the preparation of protease inhibitors, receptor antagonists, and other bioactive molecules where piperidine derivatives play a key structural role. The tosylate group serves as a good leaving group, enabling nucleophilic substitution reactions, while the benzyl carbamate (Cbz) protection ensures amine stability during transformations. Valuable in medicinal chemistry for building complex nitrogen-containing heterocycles.
