Z-L-Val-ONp

Z-L-Val-ONp is a protected amino acid derivative consisting of L-valine bearing an Nα-benzyloxycarbonyl (Z, Cbz) protecting group and a C-terminal ONp ester (p-nitrophenyl ester). The molecule contains the amino functionality masked as the carbamate, a carboxyl group converted to the p-nitrophenyl ester, and an isopropyl side chain characteristic of valine, with stereochemistry consistent with the L designation in the product name. Z-L-Val-ONp is used as an activated amino acid ester building block in peptide synthesis and related coupling studies, where the ONp ester form provides a leaving group for acyl transfer under appropriate conditions and the Z group maintains chemoselectivity during stepwise assembly of peptide intermediates.

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