Used primarily in peptide synthesis, it serves as a protected form of D-arginine. The Boc group safeguards the amino group, while the Tos group protects the guanidine side chain, preventing unwanted reactions during peptide chain assembly. This compound is particularly valuable in creating peptides with specific sequences, especially in pharmaceutical research and development. It ensures precise control over the structure and function of synthetic peptides, which are often used in drug discovery and biochemical studies. Its application is crucial in producing peptides with high purity and stability, essential for therapeutic and diagnostic purposes.
