Abstract
The present invention provides a novel method for the preparation ofF-fluoride (F) for use in radiofluorination reactions. The method of the invention finds use especially in the preparation ofF-labelled positron emission tomography (PET) tracers. The method of the invention is particularly advantageous where bulk solutions are prepared and stored in prefilled vials rather than being freshly prepared on the day of synthesis. Also provided by the present invention is a radiofluorination reaction which comprises the method of the invention, as well as a cassette for use in carrying out the method of the invention and/or the radiofluorination method of the invention on an automated radiosynthesis apparatus.
