Widely used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of sulfa drugs and other bioactive molecules. Its fluorinated aromatic structure enhances binding selectivity and metabolic stability in drug candidates. Commonly employed in the preparation of sulfonamides through reaction with amines, which are key motifs in antimicrobial and anti-inflammatory agents. Also utilized in agrochemical synthesis for creating herbicides and fungicides due to its reactivity and ability to introduce fluorinated sulfonyl groups. Its electron-withdrawing nature makes it valuable in materials science for designing liquid crystals and functional polymers with improved thermal and electronic properties.
