Used as an intermediate in pharmaceutical synthesis, particularly in the development of bioactive molecules and drug candidates. Its chlorosulfonyl functional group allows for sulfonamide bond formation, which is common in many therapeutic agents. The tert-butyl carbamate (Boc) protection on the piperidine ring enables selective reactivity and stability during multi-step syntheses. Commonly employed in medicinal chemistry for constructing structurally complex amines and heterocyclic compounds. Suitable for creating enzyme inhibitors and receptor ligands due to the conformational rigidity of the piperidine scaffold.
