Used as a chiral building block in the synthesis of peptide-based pharmaceuticals. Its protected amine group allows selective coupling in solid-phase peptide synthesis, while the carbamoyl side chain can participate in hydrogen bonding, influencing peptide conformation and biological activity. Commonly employed in the development of enzyme inhibitors and receptor ligands where aromatic and polar side chains are required for target binding. Also utilized in medicinal chemistry for structure-activity relationship (SAR) studies due to its structural similarity to phenylalanine derivatives.
