Used as a key intermediate in the synthesis of fluorinated organic compounds, particularly in pharmaceuticals and agrochemicals where fluorine substitution enhances metabolic stability and bioavailability. It serves as a source of difluorinated aryl radicals in radical-based coupling reactions, enabling the construction of complex fluorinated aromatic systems. Its sulfinate group allows for easy transformation into sulfones, sulfonamides, or other sulfur-containing derivatives, making it valuable in medicinal chemistry for drug development. Also applied in materials science for designing fluorinated functional materials with improved thermal and oxidative stability.
