Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of fluorinated active pharmaceutical ingredients (APIs) where the methylsulfonyl group acts as a directing or activating moiety. Its fluorine atoms enhance metabolic stability and membrane permeability in drug candidates. Commonly employed in agrochemicals to improve bioavailability and pest control efficacy. Also utilized in materials science for designing liquid crystals and functional organic materials due to its polarity and electronic properties.
