Description

MilliporeSigma Sigma Organics products encompass a wide range of quality reagents, solvents, catalysts, and building blocks for organic synthesis. From benchtop discovery to process development and scale-up, Sigma Organics solutions are built to meet the needs of synthetic chemists.

Trifluoromethanesulfonic acid is the strongest monoprotic organic acid. It has been synthesized by the oxidation of bis(trifluoromethylthio)mercury with aqueous hydrogen peroxide. It undergoes complete dissociation in basic solvents such as dimethyl sulfoxide, dimethylacetamide and dimethylformamide. Its dissociation in non-aqueous solvents has been studied by conductometry. On mixing trifluoromethanesulfonic acid with HNO3, it forms nitronium trifluoromethane sulfonate, which is an excellent nitrating reagent.Trifluoromethanesulfonic acid may be used as an initiator for the cationic polymerization of styrene, hexamethylcyclotrisiloxane and L,L-dilactide.
