Cas no 77826-55-2 (N,N’-Di-Boc-(L)-cystine-dimethyl Ester)

N,N’-Di-Boc-(L)-cystine-dimethyl Ester is a protected derivative of L-cystine, featuring Boc (tert-butoxycarbonyl) groups on both nitrogen atoms and methyl ester functionalities on the carboxyl groups. This compound is widely used in peptide synthesis, where its dual protection enhances stability and prevents unwanted side reactions during coupling steps. The Boc groups facilitate selective deprotection under mild acidic conditions, while the methyl esters can be hydrolyzed or transesterified as needed. Its high purity and well-defined structure make it a reliable building block for constructing disulfide bridges in peptides and proteins, ensuring controlled and efficient synthesis in both research and industrial applications.
