This compound is primarily used in peptide synthesis as a protecting group for amino acids. The Boc (tert-butoxycarbonyl) group protects the amine functionality, while the Dnp (dinitrophenyl) group protects the side chain of ornithine. This dual protection allows for selective deprotection during the synthesis process, enabling the construction of complex peptides with high precision. It is particularly useful in solid-phase peptide synthesis (SPPS), where controlled deprotection steps are crucial for building peptide chains sequentially. Additionally, it finds applications in research settings for studying peptide structure and function, as well as in the development of peptide-based pharmaceuticals.
