Used as a highly reactive intermediate in organic synthesis, particularly in the preparation of perfluorinated aromatic compounds. Its strong electron-withdrawing nature enhances reactivity in nucleophilic substitution reactions, making it valuable in pharmaceutical and agrochemical manufacturing. Commonly employed to introduce perfluoroaryl groups in cross-coupling reactions, it also serves in materials science for building functional polymers and liquid crystals with improved thermal and oxidative stability. Due to its reactivity, it is handled under controlled conditions and often used in anhydrous solvents.
