Used as a highly efficient reagent in fluorination reactions, particularly in late-stage aromatic radiofluorination for positron emission tomography (PET) imaging. It enables selective introduction of fluorine-18 into complex molecules under mild conditions, making it valuable in radiopharmaceutical synthesis. The reagent is especially effective for electron-rich arenes, offering high yields and fast reaction kinetics. Its stability and reactivity profile support applications in automated synthesis modules for clinical radiotracer production.
