Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of protease inhibitors and other biologically active molecules. Its structure allows for selective modification in peptide-based drug design, making it valuable in medicinal chemistry research. The presence of both carboxylic acid and protected amine functional groups enables stepwise coupling reactions, useful in solid-phase and solution-phase synthesis. Commonly employed in the preparation of enzyme inhibitors where the 2-chlorophenyl moiety contributes to target binding affinity.
