Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of beta-lactamase inhibitors and antiviral agents. Its protected amine and carboxylic acid functional groups make it valuable for peptide coupling and heterocyclic ring formation in medicinal chemistry. Commonly employed in solid-phase and solution-phase synthesis due to its stability and selective deprotection characteristics. Also utilized in the preparation of enzyme inhibitors and bioactive molecules targeting proteases.
