Ethyl trifluoromethanesulfonate Cas 425-75-2

Powerful ethylating agent for organic synthesis: A highly reactive alkylating agent used to ethylate amines, thioethers, and heterocycles; the triflate group serves as an excellent leaving group in nucleophilic substitution and cyclization reactions.
Ionic liquid preparation: Reacts with various nitrogen-containing bases to synthesize triflate-based ionic liquids; serves as an intermediate for the development of new materials.
Fine chemical intermediate for pharmaceuticals: Used in the synthesis of complex heterocycles and drug molecules; employed to introduce ethyl functional groups during total synthesis.
Polymer chemistry: Acts as an initiator for cationic polymerization and is used for the modification of specialty polymers.
