Description

Perfluorobutylsulfonylfluoride is a high-value fluorinated sulfonyl fluoride building block essential for advanced chemical synthesis. This compound serves as a critical precursor for introducing the highly stable and hydrophobic perfluorobutylsulfonyl group into target molecules. It is primarily utilized by researchers and manufacturers in the pharmaceutical, agrochemical, and specialty materials sectors to develop novel compounds with enhanced properties. Its unique structure makes it indispensable for creating surfactants, polymers, and active pharmaceutical ingredients (APIs) requiring specific fluorinated motifs.

Application

• Pharmaceutical Intermediate: Key building block for synthesizing novel drug candidates, particularly sulfonamide-based therapeutics.
• Agrochemical Synthesis: Used in the production of advanced pesticides and herbicides with improved environmental stability and efficacy.
• Polymer & Material Science: Serves as a monomer or modifier for creating fluorinated polymers, surfactants, and coatings with exceptional oil, water, and chemical resistance.
• Lithium-Ion Battery Electrolytes: Employed in the development of novel electrolyte additives and salts to enhance battery performance and safety.
• Organic Synthesis Reagent: A versatile reagent for introducing sulfonyl fluoride functional groups in complex molecule construction, useful in click chemistry and bioconjugation.
• Surface Treatment Agents: Used to manufacture fluorinated surface modifiers that provide low surface energy and repellency properties.

Quality Control

Our Perfluorobutylsulfonylfluoride is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing including GC, NMR, and FT-IR to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided with every shipment. We adhere to cGMP guidelines where applicable to support our customers in regulated industries.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Keep away from heat, sparks, and open flame. This material is moisture-sensitive and reacts with strong bases; ensure the container is sealed under an inert atmosphere such as nitrogen to prevent hydrolysis and maintain purity.
