Used as an intermediate in pharmaceutical synthesis, particularly in the development of active pharmaceutical ingredients (APIs) where protected piperidine scaffolds are required. The Boc-protected amine group allows selective reactivity at other sites, while the methanesulfonyloxymethyl group serves as a good leaving group for nucleophilic substitution reactions. Commonly employed in the preparation of kinase inhibitors, CNS-targeted drugs, and other bioactive molecules requiring a functionalized piperidine moiety. Its stability and reactivity profile make it suitable for multi-step synthetic routes in medicinal chemistry.
