Used primarily as an intermediate in organic synthesis, especially in pharmaceutical development. It enables the introduction of chlorosulfonyl functionality in piperidine-based structures, which can be further modified to create bioactive molecules. Commonly employed in the preparation of sulfonamide derivatives, which are key motifs in drug discovery due to their biological activity. Its Boc-protected amine allows for selective reactions at other sites without interference, making it valuable in multi-step syntheses of complex medicinal compounds. Frequently utilized in the development of receptor agonists, antagonists, and enzyme inhibitors.
