Used as a key intermediate in the synthesis of peptide-based pharmaceuticals, particularly in the development of targeted cancer therapies and protease inhibitors. Its protected amine group allows for selective coupling in solid-phase peptide synthesis, while the carbamoyl side chain can participate in hydrogen bonding, enhancing binding specificity to biological targets. Commonly employed in the preparation of enzyme inhibitors and receptor agonists where precise side chain functionality is required. Also utilized in the production of diagnostic agents and bioconjugates due to its compatibility with various coupling reagents and mild deprotection conditions.
