Fmoc-OSu, also known as N-(9-Fluorenylmethoxycarbonyloxy)succinimide, is a high-purity Fmoc transfer reagent used for amine protection, amino acid derivatization, peptide synthesis, and biomolecule functionalization. It is commonly used to introduce the Fmoc protecting group onto amino acids, peptides, and other amine-containing molecules.

As a reactive succinimidyl ester, Fmoc-OSu enables efficient and selective N-terminal or amine functionalization under suitable reaction conditions. It is widely used in Fmoc-based solid-phase peptide synthesis (SPPS), medicinal chemistry, bioorganic chemistry, chemical biology, biomaterial functionalization, and peptide reagent preparation.
