Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of protease inhibitors and other biologically active molecules. Its structure supports peptide mimetic design, making it valuable in medicinal chemistry for creating analogs with enhanced stability and binding affinity. Commonly employed in solid-phase and solution-phase peptide synthesis where protection of the amine group is required. The chlorophenyl moiety can influence target selectivity in drug candidates, especially in central nervous system agents and enzyme inhibitors.
