Z-S-benzyl-L-cystein is a protected amino acid derivative of L-cysteine in which the amino group is carbobenzoxy (Z, benzyloxycarbonyl) protected and the thiol side chain is benzylated as a thioether (S-benzyl). The molecule contains a free carboxyl group and a thioether-functionalized sulfur that replaces the cysteine thiol, while the Z group masks the α-amino functionality to control chemoselectivity during peptide-related transformations. Z-S-benzyl-L-cystein is used as a cysteine-bearing building block for preparing peptide intermediates and cysteine-containing peptide analogues in contexts where protection of both the α-amino group and the sulfur side chain is required to support stepwise synthesis and subsequent deprotection strategies.
