Description

1,1,2,2,3,3,4,4-Octafluorobutane-1-Sulphonic Anhydride is a high-purity, reactive fluorinated sulfonic acid derivative, serving as a critical building block for advanced chemical synthesis. Its primary value lies in its ability to introduce perfluorobutylsulfonyl groups, enabling the creation of novel materials with enhanced properties. This specialized reagent is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors who require precise fluorination and sulfonylation capabilities.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for introducing fluorinated sulfonamide or sulfonate ester functionalities to modulate bioavailability and metabolic stability.
• Agrochemical Synthesis: Used in creating novel herbicides, fungicides, and insecticides where the perfluorobutylsulfonyl moiety can enhance lipophilicity and environmental persistence.
• Polymer & Material Science: Serves as a monomer or modifying agent for producing specialty fluoropolymers, ion-exchange membranes, and surface-active agents with unique chemical resistance and thermal stability.
• Lithium-Ion Battery Electrolytes: Potential application in the development of novel lithium salts (e.g., LiFBSI analogs) for next-generation electrolyte formulations aimed at improving battery safety and performance.
• Catalyst & Ligand Preparation: Employed in the synthesis of specialized Lewis acid catalysts or ligands used in asymmetric synthesis and polymerization reactions.
• Surface Modification: Used to create hydrophobic and oleophobic coatings on various substrates, including textiles, electronics, and optical components.

Quality Control

Our 1,1,2,2,3,3,4,4-Octafluorobutane-1-Sulphonic Anhydride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure high purity and consistency, meeting the stringent requirements for research and industrial synthesis. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment. We can support development projects with custom purity grades and analytical method development upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis and degradation. Keep away from strong bases and sources of ignition.
