Z-Cys(Z)-OH is a protected cysteine derivative featuring a thiol-containing side chain (cysteine class) in which the amino group is masked as a benzyloxycarbonyl (Z) carbamate and the carboxyl group is present as a free acid (-CO2H). The side-chain sulfur is further protected as a benzylic thioether (Z on sulfur), giving the molecule two Z-protecting groups that suppress thiol oxidation and reduce undesired chemoselective reactions during peptide coupling steps. In peptide chemistry and chemical biology workflows, this compound functions as a protected amino acid building block and precursor for preparing cysteine-containing peptides or cysteine-functionalized intermediates where controlled deprotection and subsequent conjugation or labeling are required.
