Used primarily as a fluorinated building block in organic synthesis, especially in the development of specialty surfactants and surface modifiers. Its dual bromo and thioether functional groups enable cross-coupling reactions, making it valuable in constructing complex fluorinated molecules for applications in water- and oil-repellent coatings, high-performance lubricants, and hydrophobic additives in polymers. The long perfluorinated chains contribute to strong surface activity and thermal stability, useful in aerospace, electronics, and protective coating industries.
