Product Overview
Fmoc-Ser(tBu)-OSu CAS: 158000-21-6
Applications
An activated ester derivative of serine used in peptide synthesis and bioconjugation. The N-hydroxysuccinimide (NHS/OSu) ester acts as an efficient leaving group, allowing direct, mild coupling with primary amines without needing external activation reagents. The acid-labile tert-butyl (tBu) ether protects the side-chain hydroxyl group, while the base-labile Fmoc group allows step-by-step chain extension.
Quality Assurance
