Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of protease inhibitors and other bioactive molecules. Its carboxylic acid and protected amine functional groups allow for selective coupling reactions, making it valuable in solid-phase peptide synthesis and medicinal chemistry. The Boc-protected amine ensures stability during reactions and can be easily deprotected under mild acidic conditions, enabling stepwise assembly of complex molecules. Commonly employed in the preparation of drug candidates targeting viral infections and cancer.
