This chemical is primarily used in peptide synthesis, particularly in solid-phase peptide synthesis (SPPS). It serves as a protected amino acid derivative, where the Boc (tert-butyloxycarbonyl) group protects the amine functionality, and the Fmoc (fluorenylmethyloxycarbonyl) group protects the side chain of ornithine. This dual protection allows for selective deprotection during the synthesis process, enabling the stepwise construction of peptides with high precision. It is especially valuable in the synthesis of complex peptides and peptidomimetics, where orthogonality of protecting groups is crucial. Additionally, it finds applications in the development of peptide-based drugs, biomaterials, and research tools in biochemistry and molecular biology.
