Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of peptide-based drugs and enzyme inhibitors. Its protected amine and carboxylic acid functionalities allow for selective coupling reactions, making it valuable in solid-phase and solution-phase peptide synthesis. The cycloheptyl group provides structural rigidity and lipophilicity, which can enhance metabolic stability and bioavailability in drug candidates. Commonly employed in research settings for structure-activity relationship (SAR) studies.
