Z-L-Nle-ONp is a protected amino acid derivative in which the amino acid is the L-form of norleucine (Nle) bearing a benzyloxycarbonyl (Z, Cbz) protecting group on the α-amino functionality and an ONp ester (p-nitrophenyl ester) at the carboxyl group. The molecule therefore contains a carbamate-protected amine and an activated carboxylate ester, with the side chain featuring a straight-chain aliphatic functionality typical of norleucine and a stereocenter consistent with the L designation. Z-L-Nle-ONp is commonly used as a building block for peptide coupling and as a substrate-like activated amino acid derivative in synthetic workflows where the p-nitrophenyl ester can serve as a leaving-group-bearing carboxyl activation handle, including preparation of peptide-related intermediates and derivatized amide products.
