Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of protease inhibitors and other biologically active molecules. Its functional groups allow for selective peptide coupling and protection strategies in solid-phase and solution-phase peptide synthesis. The Boc and Cbz protecting groups enable stepwise assembly of complex molecules by preventing unwanted side reactions during multi-step syntheses. Commonly employed in the preparation of drug candidates targeting viral infections, cancer, and neurological disorders.
