This chemical is primarily used in peptide synthesis as a protected amino acid derivative. It serves as a building block for constructing peptides, ensuring specific functional groups remain intact during the synthesis process. The Boc (tert-butoxycarbonyl) group protects the amine functionality, while the 2-chlorobenzyloxycarbonyl (2-Cl-Z) group safeguards the side chain of ornithine. This protection allows for selective deprotection and modification, enabling the creation of complex peptide structures. It is particularly useful in research and pharmaceutical development, where precise control over peptide sequences is essential for studying biological activity or developing therapeutic agents.
