Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) where fluorinated aromatic compounds enhance metabolic stability and bioavailability. Its sulfonic acid group facilitates salt formation and improves solubility, making it valuable in drug design. Also employed in agrochemical synthesis to create herbicides and pesticides with improved efficacy and environmental profiles. Additionally, serves as a building block in materials science for designing functional polymers and specialty chemicals requiring thermal and chemical resistance.
