Applications · 3 items

UsesPotassium trifluoromethanesulfonate is used as a reagent in the synthesis of guanine-quadruplex hybrid materials. It acts as a supporting electrolyte in the electrochemical study of evidence for gold anion in ethylenediamine. It is involved in the preparation of N-fluoro-2,4,6-trimethylpyridinium triflate by reacting with 2,4,6-trimethyl-pyridine. Further, it is used in the preparation of imidazolium salt, 3-methyl-1-(3R,3aR,6S,6aR)-[6-(benzyloxy)-hexahydrofuro[3,2-b]furan-3-yl]imidazolium trifluoromethanesulfonate.

UsesPotassium trifluoromethanesulfonate is used in studies of mixed alkali effects and short range interactions in poly(ethylene oxide) electrolytes,1 and characteristics of the electrochemical behavior of glassy carbon in super-acid media.

General DescriptionPotassium trifluoromethanesulfonate (KOTf, potassium triflate) is the potassium salt of trifluoromethanesulphonic acid. It has been prepared by neutralizing a warm aqueous solution of trifluoromethanesulphonic acid with potassium carbonate. The structure of siloxane–poly(oxyethylene) hybrids doped with potassium triflate has been investigated.
