Used in peptide synthesis as a protecting group for cysteine residues. The Boc group safeguards the amino group, while the Dpm (diphenylmethyl) group protects the thiol side chain, preventing unwanted reactions during peptide chain assembly. This compound is particularly valuable in solid-phase peptide synthesis (SPPS) to ensure selective deprotection and controlled coupling of amino acids. It is also employed in the synthesis of complex peptides and proteins, where cysteine plays a critical role in disulfide bond formation, structural stability, and biological activity. Additionally, it is utilized in the preparation of peptide-based drugs, biomaterials, and research tools for studying protein interactions and functions.
