Used as an intermediate in the synthesis of peptide-based pharmaceuticals, particularly in the preparation of modified amino acids and bioconjugates. Its protected amine and carboxyl functionalities allow selective coupling reactions, making it valuable in solid-phase peptide synthesis. Commonly employed in the development of protease inhibitors and targeted drug delivery systems due to its stability and biocompatibility. Also utilized in the construction of branched peptides and dendrimers for biomedical applications.
