Z-L-Gln-OSu

Z-L-Gln-OSu is a protected amino acid derivative in which L-glutamine is converted to a glutaminyl N-carboxyanhydride-type activated ester (OSu) while the α-amino group is protected by a benzyloxycarbonyl (Z, Cbz) group. The molecule contains a free carboxylate equivalent as the N-succinimidyl ester (OSu) and a side-chain amide functionality characteristic of glutamine, with the stereochemistry indicated as L in the product name. Z-L-Gln-OSu is used as an activated amino acid building block for peptide coupling and for preparing glutaminyl-containing peptide intermediates or conjugates in solution-phase or solid-phase synthesis workflows where an electrophilic ester enables amide bond formation with nucleophiles.
