Z-L-Pro-ONp is a protected amino acid derivative consisting of L-proline bearing an N-benzyloxycarbonyl (Z, Cbz) protecting group and an ONp ester at the carboxylate, forming a proline-based amino acid ONp ester. The molecule contains a carbamate-protected amino functionality and a carboxylate ester linkage to the p-nitrophenyl (ONp) leaving group, with stereochemistry consistent with the L-proline configuration indicated in the name. Z-L-Pro-ONp is used as an activated proline building block in peptide synthesis and related coupling workflows, where the ONp ester can participate in acyl transfer chemistry to assemble peptide bonds under appropriate conditions.
