Description

Nonafluorobutanesulfonic Anhydride 97 is a high-purity, reactive fluorinated sulfonic acid derivative. This compound serves as a critical reagent for introducing the nonafluorobutanesulfonyl (nonaflate) group, a powerful leaving group and protecting moiety in advanced organic synthesis. It is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries who require precise fluorination and sulfonylation reactions. The product is supplied with a minimum purity of 97% to ensure consistent performance and reliable results.

Application

• Pharmaceutical Intermediate Synthesis: Key reagent for creating nonaflate esters and amides as intermediates in active pharmaceutical ingredient (API) development.
• Agrochemical Manufacturing: Used in the synthesis of fluorinated herbicides, pesticides, and fungicides to enhance biological activity and stability.
• Polymer Chemistry: Acts as a monomer or modifier in the production of specialty fluoropolymers and ion-exchange membranes.
• Catalyst and Ligand Preparation: Employed to synthesize novel fluorinated ligands and organocatalysts for asymmetric synthesis.
• Material Science Research: Utilized in surface modification and the creation of superhydrophobic or oleophobic coatings.
• Electrolyte Additive: Investigated for use in lithium-ion battery electrolytes to improve performance and safety.

Quality Control

Our Nonafluorobutanesulfonic Anhydride 97 is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR, IR, and HPLC analysis, to verify identity, purity, and the absence of critical impurities. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing all relevant specifications. Our quality commitment ensures the material meets the high standards required for research and industrial-scale applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be handled under a dry inert atmosphere (e.g., nitrogen or argon) to prevent decomposition. Keep away from strong bases and incompatible materials.
