Used primarily in peptide synthesis, this compound serves as a protected form of cysteine, ensuring selective reactivity during the formation of peptide bonds. The Boc group protects the amino group, while the pMeOBzl group safeguards the thiol side chain, preventing unwanted side reactions. It is particularly valuable in the synthesis of complex peptides and proteins, where precise control over cysteine residues is crucial. Its application extends to the development of pharmaceuticals, including peptide-based drugs, where maintaining the correct structure and functionality is essential. Additionally, it is employed in research settings for studying peptide interactions and folding mechanisms.
