Z-L-Leu-ONp

Z-L-Leu-ONp is a protected amino acid derivative based on L-leucine in which the α-amino group is carbobenzyloxy (Z, benzyloxycarbonyl) protected and the carboxyl group is converted to a p-nitrophenyl (ONp) ester. The molecule therefore contains a Z-protected amino functionality and an esterified carboxyl group bearing the p-nitrophenoxy leaving group, with the side chain characteristic of leucine (isobutyl) providing hydrophobic functionality. Z-L-Leu-ONp is used as an activated amino acid ester building block in peptide coupling workflows and as a substrate for studying ester reactivity or p-nitrophenyl ester behavior under conditions that promote aminolysis or acyl transfer.
