Used in peptide synthesis as a protected form of ornithine to prevent unwanted reactions during the formation of peptide bonds. It is particularly valuable in the production of complex peptides and proteins, where selective protection and deprotection of functional groups are required. Additionally, it serves as an intermediate in the synthesis of various biologically active compounds and pharmaceuticals, including enzyme inhibitors and antimicrobial agents. Its role in research and development of therapeutic peptides highlights its importance in medicinal chemistry.
