Used primarily as a reagent in organic synthesis, particularly in the preparation of sulfone derivatives for pharmaceuticals and agrochemicals. Its electron-withdrawing trifluoroethyl sulfone group facilitates carbon-carbon bond formation in cross-coupling reactions. It serves as a building block in the development of bioactive molecules, leveraging the stability and polarity imparted by the trifluoromethyl and sulfonyl groups. Also employed in materials science for designing functional polymers with enhanced thermal and oxidative stability.
