Descripción

General description

Methyl trifluoromethanesulfonate is a strong methylating reagent, commonly used for the pre-methylation of polysaccharides under mild basic conditions.

Application

Methyl trifluoromethanesulfonate can be used as a methylation reagent:

• In the determination of polysulfides, zerovalent sulfur in sulfide-rich water wells, and polysulfide species in electrolyte of a lithium–sulfur battery using chromatography-based techniques.
• In reactions with potassium enolates.
• For the conversion of amines to methyl ammonium triflates.
