Used as a protective agent in peptide synthesis, specifically for safeguarding the amino groups of arginine during chemical reactions. This ensures the selective formation of peptide bonds without unwanted side reactions. It is particularly valuable in the production of complex peptides and proteins, where precise control over amino acid reactivity is essential. Additionally, it aids in the study of arginine's role in biological processes by allowing researchers to isolate and modify its structure in a controlled manner. Its application extends to pharmaceutical development, where it helps create peptide-based drugs with enhanced stability and efficacy.
