Z-Pyr-OSu

Name: Z-Pyr-OSu
Brand: Creative Peptides
Rating: 5 (1 reviews)

Z-Pyr-OSu is a protected amino-acid derivative featuring a Z (benzyloxycarbonyl, Cbz) carbamate-protected pyridyl-containing amino acid scaffold linked to an activated N-hydroxysuccinimide (OSu) ester. The molecule contains a carbamate-protecting group on the amino functionality and an OSu ester at the carboxylate position, providing a leaving group suitable for acyl transfer chemistry while retaining the pyridyl side-chain functionality for subsequent coordination or derivatization. In synthesis and chemical biology workflows, Z-Pyr-OSu is used as an activated amino-acid building block or intermediate to prepare amide-containing conjugates and peptide-related derivatives under conditions that promote reaction at the OSu ester.

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