Trifluoromethanesulfonic  acid, also known as triflic acid, TFMS, TFSA, HOTf or TfOH, is a sulfonic acid with the chemical formula CF3SO3H. It is often regarded as one of the strongest acids, and is one of a number of so-called "superacids". it is used in the manufacture of pharmaceuticals, agricultural chemicals and polymers. The anhydrous form is widely used in fine chemical synthesis. It is non-oxidizing, has a high thermal stability, and is resistance to both oxidation and reduction, which makes it one of the more useful compounds in the super acids class. In the pharma industry, it is used to make a number of drug classes, including nucleosides, antibiotics, steroids, proteins and glycosides. Triflic anhydride reacts readily with water and has an unfavorable toxicity profile.
It is used for organic synthesis, widely used in pharmaceutical and chemical industries, such as nucleosides, antibiotics, steroids, protein, sugar, vitamins synthesis, silicone rubber modification.
Isomerization and alkylation of the catalyst, the preparation of 2, 3-dihydro-2-indanone, tetralone, glycosides in the removal of glycoproteins.
Acid catalyst for the industry, Intermediate for liquid crystals, Pharmaceuticals intermediates, Intermediate for organic synthesis. One of the strongest available monoprotic acids.
As a catalyst in Friedel-Crafts type acylation, alkylation and polymerization reactions; as a solvent for ESR; as a nonaqueous strong acid titrant; with trifluoroacetic  acid, q.v., in solid-phase peptide synthesis.
Trifluoromethanesulfonic  acid acts as a catalyst for esterification reactions and an acidic titrant in nonaqueous acid-base titration. It is useful in protonations due to the presence of conjugate base triflate is non nucleophilic. It serves as a deglycosylation agent for glycoproteins. In addition, it is a precursor and a catalyst in organic chemistry. It reacts with acyl halides to prepare mixed triflate anhydrides, which are strong acylating agents used in Friedel-Crafts reactions. It acts as a key starting material for the preparation of ethers and olefins by reacting with alcohols as well as to prepare trifluoromethanesulfonic anhydride by dehydration reaction.
