Best Triflic Acid CAS 1493-13-6

Triflic Acid, also known as trifluoromethanesulfonic acid, is a strong organic acid with the molecular formula CF3SO3H, easily soluble in water and low in toxicity.

It is a hygroscopic colorless liquid at room temperature, yellow or yellow-brown liquid when it contains impurities, and fumes in the air.

Triflic Acid is one of the known super acids. Because of its strong thermal and chemical stability, it and its conjugate base have many uses.

Triflic Acid also does not easily sulfonate other substances, so there is no need to worry about this reaction as when using sulfuric acid, fluorosulfuric acid and chlorosulfonic acid.

However, the rapid addition of Trifluoromethanesulfonic Acid to polar solvents can be dangerous due to the highly exothermic dissolution process of Trifluoromethanesulfonic Acid.

Therefore, the reagent should be stored in disposable vials or teflon bottles, and should be used in a fume hood.
