Used as a fluorinated sulfonylating agent in organic synthesis, particularly in the preparation of sulfonamides and sulfonate esters. Its electron-withdrawing difluoromethanesulfonyl group enhances reactivity in electrophilic substitution reactions. Commonly employed in pharmaceutical and agrochemical industries to introduce fluorinated sulfone functionalities that improve metabolic stability and lipophilicity of target molecules. Also utilized in materials science for modifying polymers and liquid crystals due to its thermal and chemical stability.
