Z-Lys-ONp · HCl is a protected lysine derivative in which the α-amino group is carbobenzyloxy (Z/Cbz) protected and the carboxyl group is converted to an ONp ester (p-nitrophenyl ester), forming a hydrochloride salt. The molecule contains the ε-amino side chain of lysine in its unprotected form, while the α-amino functionality is masked by the Z protecting group and the ONp ester bears a p-nitrophenyl leaving group under acyl-transfer conditions; the "Z-" prefix indicates the N-protection pattern but does not specify a stereochemical configuration. As an activated amino acid ester, it is used as an acylating building block for peptide coupling or for preparing lysine-containing amide derivatives, and the ONp group provides a convenient handle for analytical monitoring of ester reactivity and for stepwise synthesis of more complex amino acid and peptide intermediates.
