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 drug candidates with improved stability and bioavailability. Commonly employed in solid-phase and solution-phase peptide synthesis where protection of the amino group is required. The fluorophenyl moiety enhances binding selectivity in target molecules, useful in optimizing pharmacokinetic properties.
