Description

Undecafluorocyclohexanesulphonyl Fluoride is a highly fluorinated cyclic sulfonyl fluoride derivative, serving as a critical building block in advanced chemical synthesis. This compound is valued for its unique reactivity, enabling the introduction of perfluorocyclohexyl sulfonyl groups to create materials with exceptional stability and specific functional properties. It is primarily sought by R&D chemists and process engineers in the pharmaceutical, agrochemical, and specialty polymer industries for developing novel active ingredients and high-performance materials.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs), particularly for introducing fluorinated sulfonamide or sulfonate ester moieties to modulate bioavailability and metabolic stability.
• Agrochemical Synthesis: Serves as a key precursor for creating novel herbicides, fungicides, and insecticides where the perfluorocyclohexyl group enhances lipophilicity and environmental persistence.
• Polymer Modification: Employed to synthesize specialty monomers for fluoropolymers, imparting oil, water, and chemical resistance to coatings, membranes, and elastomers.
• Surface Treatment Agent: Acts as a coupling agent or surface modifier to create low-surface-energy coatings for textiles, electronics, and aerospace components.
• Lithium-Ion Battery Electrolytes: Investigated as a potential additive or co-solvent to improve electrolyte stability and safety in high-voltage battery systems.
• Organic Synthesis Reagent: Functions as a versatile electrophile in nucleophilic substitution reactions to construct complex fluorinated molecules for material science and catalysis.

Quality Control

Our Undecafluorocyclohexanesulphonyl Fluoride is manufactured under controlled conditions to ensure batch-to-batch consistency and high purity. Quality is assured through a comprehensive analytical regimen including NMR, GC, and FTIR spectroscopy. A detailed Certificate of Analysis (COA) documenting identity, purity, and impurity profiles is provided with each shipment to support your quality management systems.

Storage

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