Product Overview
tBuO-C20-Glu(OtBu)-OSu CAS No. : 1119061-72-1

Applications
Peptide Synthesis Intermediate: Used as an activated NHS-ester derivative of the C20 diacid glutamate side chain. It is key intermediate in the conjugation of lipophilic side chains onto peptide backbones (such as Tirzepatide and other GLP-1/GIP dual or triple agonists) to promote albumin binding and extend half-life.
