This chemical is primarily used in peptide synthesis as a protected form of D-arginine. The Boc (tert-butoxycarbonyl) group safeguards the amino group during the synthesis process, while the nitro group protects the guanidine moiety. It is particularly valuable in creating peptides with specific configurations, as the D-arginine enantiomer can influence the peptide's biological activity and stability. Additionally, it is employed in research to study enzyme-substrate interactions, particularly in cases where arginine plays a critical role, such as in nitric oxide synthase studies. Its protective groups allow for selective deprotection, enabling precise control over the synthesis of complex peptide structures.
