Used in peptide synthesis as a protected intermediate, enabling selective coupling reactions in the development of complex organic molecules. The Boc (tert-butoxycarbonyl) group provides amine protection, while the 3-chlorobenzyl moiety can influence conformational stability or serve as a structural component in bioactive compounds. Commonly applied in medicinal chemistry for designing protease inhibitors or receptor ligands where proline derivatives modulate biological activity. Its DL-configuration allows for racemic screening in early-stage drug discovery to assess structure-activity relationships.
