Description

N,N-Dimethyl-1,1,2,2,2-pentafluoroethanesulfonamide (CAS No. 1270179-76-4) is a highly fluorinated sulfonamide compound with the molecular formula C₄H₆F₅NO₂S. This specialty chemical is characterized by its unique pentafluoroethyl group attached to a sulfonamide backbone, making it a valuable intermediate in organic synthesis and fluorochemical research. The compound exhibits exceptional thermal and chemical stability due to the presence of strong carbon-fluorine bonds, making it suitable for applications requiring inert and non-reactive materials.

With a purity of ≥95% (GC), this product is supplied as a clear, colorless to pale yellow liquid under standard conditions. It is soluble in common organic solvents such as dichloromethane, THF, and acetonitrile but exhibits limited solubility in water. Researchers will appreciate its utility in the development of novel fluorinated materials, electrolytes, and pharmaceuticals where fluorine incorporation is desired for enhanced properties such as lipophilicity, metabolic stability, or electronic effects.

Proper storage recommendations include keeping the product in a tightly sealed container under inert atmosphere at 2-8°C to maintain stability. Safety data sheets are available upon request, and all handling should be performed in a well-ventilated fume hood with appropriate personal protective equipment due to the potential hazards associated with fluorinated compounds.
