Z-L-Trp-OSu is a protected amino acid derivative consisting of L-tryptophan bearing a benzyloxycarbonyl (Z, Cbz) protecting group on the amino functionality and an N-hydroxysuccinimide (OSu) ester at the carboxyl position, classifying it as an amino acid N-hydroxysuccinimide ester. The molecule contains a Z-carbamate that masks the α-amino group, a carboxyl-derived OSu ester that provides an activated acyl leaving group, and the indole side chain characteristic of tryptophan, with stereochemistry indicated as L at the α-carbon. Z-L-Trp-OSu is employed in peptide coupling and amide-bond formation workflows where the OSu ester can transfer the tryptophan acyl group to nucleophiles such as amines, supporting synthesis of tryptophan-containing peptide intermediates and chemically labeled or conjugated biomolecules.
