Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of protease inhibitors and other bioactive molecules. Its azido group allows for click chemistry applications, enabling efficient conjugation in drug discovery research. The protected amine and ester functionalities make it suitable for peptide coupling and solid-phase synthesis, especially in constructing complex organic molecules with stereochemical control. Commonly employed in medicinal chemistry for building chiral scaffolds in antiviral and anticancer agents.
