Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of bioactive molecules requiring piperidine ring modifications. Its chlorosulfonyl group enables selective sulfonamide bond formation, making it valuable in medicinal chemistry for creating enzyme inhibitors or receptor ligands. The benzyl-protected carboxylic acid allows for controlled deprotection and further functionalization in multi-step synthetic routes. Commonly applied in research settings for designing drug candidates targeting central nervous system disorders and metabolic diseases.
