Description

Perfluoro-1-Octanesulfonyl Fluoride is a high-value perfluorinated sulfonyl fluoride building block, essential for introducing the perfluorooctylsulfonyl group into target molecules. This compound is critical for synthesizing advanced materials with exceptional chemical resistance, thermal stability, and low surface energy. It is primarily sought after by R&D and production teams in the pharmaceutical, agrochemical, and specialty polymer industries for creating surfactants, electrolytes, and novel fluorinated intermediates.

Application

• Key Intermediate for Fluorinated Surfactants and Polymers: Serves as a foundational reagent for synthesizing perfluorooctanesulfonamide derivatives, which are precursors to stain-resistant coatings, oil-repellent fabrics, and high-performance fluoropolymers.
• Pharmaceutical and Agrochemical Synthesis: Used to incorporate the perfluorooctylsulfonyl moiety into bioactive molecules, potentially altering their pharmacokinetics, metabolic stability, and membrane permeability.
• Lithium-Ion Battery Electrolyte Additives: Employed in the development of novel sulfonylimide-based lithium salts (e.g., analogues of LiTFSI) for next-generation electrolytes that enhance battery safety and performance.
• Surface Modification and Coatings: Acts as a coupling agent to impart permanent hydrophobic and oleophobic properties to surfaces of glass, metals, and textiles.
• Production of Perfluoroalkanesulfonyl Chlorides and Amides: A versatile starting material for generating a suite of other valuable perfluorinated sulfonyl derivatives through nucleophilic substitution reactions.
• Research and Development of Advanced Materials: Utilized in academic and industrial labs for creating novel fluorinated ionic liquids, catalysts, and porous framework materials.

Quality Control

Every batch of Perfluoro-1-Octanesulfonyl Fluoride is manufactured and tested under a strict quality management system. We ensure high purity and consistency through advanced analytical techniques including GC, HPLC, and NMR. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent decomposition.
