Used as an intermediate in organic synthesis, particularly in pharmaceutical and agrochemical manufacturing. It serves as a building block in the production of sulfone-based compounds with biological activity. Commonly employed in cross-coupling reactions due to the stability of the sulfone group, enabling the formation of carbon-carbon bonds. Also utilized in the development of functional materials and as a reagent in research laboratories for modifying molecular structures. Its electron-withdrawing nature makes it valuable in directed ortho-metalation processes.
