Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. It serves as a building block in the formation of sulfone-based compounds, which are valuable in drug development due to their metabolic stability and biological activity. Commonly employed in Julia olefination reactions, Michael additions, and other carbon-carbon bond-forming processes, it enables the synthesis of complex molecules such as styrene derivatives and bioactive alkenes. Its stability and reactivity make it suitable for use in research laboratories and industrial-scale synthesis.
