Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of protease inhibitors and other biologically active compounds. Its fluorinated aromatic structure enhances binding selectivity and metabolic stability in drug molecules. Also employed in agrochemicals for the production of herbicides and fungicides due to its electron-withdrawing sulfonamide group and fluorine substitution pattern. Additionally, serves as a building block in materials science for designing specialty polymers with improved thermal and oxidative resistance.
