What Is N-Fmoc-succinimide?
N-Fmoc-succinimide (CAS 82911-69-1), commonly abbreviated Fmoc-OSu, is 9-fluorenylmethyl succinimidyl carbonate—an activated carbonate used to introduce the Fmoc (9-fluorenylmethoxycarbonyl) protecting group onto amino groups. Molecular formula C19H15NO5; molecular weight about 337.33 g/mol. Always match CAS 82911-69-1 on the batch COA.
Supplier and peptide-chemistry literature describe Fmoc-OSu as a standard reagent for preparing Fmoc-amino acids and for solid-phase peptide synthesis (SPPS) workflows. Compared with Fmoc-Cl, Fmoc-OSu is often preferred for cleaner Fmoc installation with reduced dipeptide contamination in amino-acid protection. It is also cited in glycopeptide and related protection chemistry. Monuo Chemical supplies N-Fmoc-succinimide as a specialty chemical raw material under Custom synthesis, with batch identity documentation (COA / SDS). Finished-product claims remain the customer’s responsibility. Confirm assay against the batch COA for your intended method.

Handling & Use Notes
- Assay check: Confirm purity / assay for N-Fmoc-succinimide on the batch COA before use.
- Moisture control: Activated carbonate reagents are moisture-sensitive; keep sealed and minimize humidity exposure during sampling.
- Process fit: Verify solvent compatibility (e.g., DMF / DCM systems commonly used in Fmoc chemistry) before scale-up.
- Safety: Follow the SDS for storage, PPE and waste handling. Use the batch SDS as the controlling safety document.

Frequently Asked Questions
What is N-Fmoc-succinimide (CAS 82911-69-1)?
It is Fmoc-OSu, an activated succinimidyl carbonate used to install the Fmoc protecting group on amino compounds. Monuo Chemical lists it under Custom synthesis. Match CAS 82911-69-1 on the batch COA.
Is Fmoc-OSu the same material?
Yes. Fmoc-OSu / Fmoc-OSu and N-(9-fluorenylmethoxycarbonyloxy)succinimide are common catalog names. Always put CAS 82911-69-1 on RFQs.
Where is it typically used?
Typical uses include Fmoc-amino-acid preparation and solid-phase peptide synthesis reagent supply. Finished-product claims remain the customer’s responsibility.
Why choose Fmoc-OSu instead of Fmoc-Cl?
Literature often cites cleaner Fmoc introduction and lower dipeptide by-product formation versus Fmoc-Cl. Validate the reagent for your specific substrates.
