Z-D-Arg-OH · HCl is a protected, free-form amino acid derivative consisting of D-arginine bearing a benzyloxycarbonyl (Z, Cbz) protecting group on the α-amino functionality and existing as the hydrochloride salt, with the side chain retaining the guanidinium group. The molecule contains a carboxylic acid (-COOH) and a guanidinium side chain (-C(=NH)NH2) that is strongly basic, while the Z group masks the α-amino group to reduce undesired side reactions during coupling chemistry. As a salt-stabilized, protected amino acid building block, it is used in peptide synthesis workflows to introduce D-arginine residues and to provide a protected handle that can be deprotected or incorporated under stepwise assembly conditions, while the guanidinium functionality supports studies requiring arginine-like charge and hydrogen-bonding features.
