Sodium trifluoromethanesulfonate
Sodium trifluoromethanesulfonate (CAS: 2926-30-9), known as sodium triflate, is the sodium salt of trifluoromethanesulfonic acid, combining the weakly coordinating triflate anion with a readily available alkali cation. This white, highly water-soluble salt serves multiple roles in chemical synthesis, electrochemistry, and materials science. In organic synthesis, it acts as a mild base and triflate source for metal-catalyzed transformations, while its high solubility in both water and polar organics makes it useful in phase-transfer scenarios. Electrochemical researchers employ sodium triflate as a supporting electrolyte in aqueous and non-aqueous systems, including battery and capacitor studies where its electrochemical stability window is advantageous. The compound also serves as a precursor for triflate-containing ionic liquids and as a catalyst component in esterification and condensation reactions. With its stability, solubility profile, and low nucleophilicity, sodium triflate is a practical reagent for diverse laboratory and industrial processes.
