Z-Lys-OBzl · benzenesulfonate

Z-Lys-OBzl · benzenesulfonate is a protected lysine derivative featuring an Nα-benzyloxycarbonyl (Z) amino protecting group and a C-terminal benzyl ester (OBzl), with the side chain terminating in a primary ε-amino group characteristic of lysine. The molecule is present as a benzenesulfonate salt, which associates with the basic ε-amino functionality, while the free carboxylate is masked as an ester and the amino functionality is protected at the α-position. In peptide synthesis workflows, this salt-protected amino acid ester is used as a stepwise building block to control chemoselectivity and to introduce the lysine side chain for subsequent deprotection and peptide coupling, and the salt form can support handling and characterization in analytical and preparative contexts.

Designed for biological research and industrial applications, not intended for individual clinical or medical purposes.
