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. Commonly employed in solid-phase and solution-phase peptide synthesis due to the presence of the Boc (tert-butoxycarbonyl) protecting group, which enables controlled deprotection and coupling steps. Also utilized in the preparation of enzyme inhibitors and receptor ligands targeting neurological and metabolic disorders.
