The present disclosure relates to a solid-phase process for the production of radiolabeled tracers, in particular for the production of
18
F-labeled compounds which may be used as Positron Emission Tomography (PET) radiolabeled tracers. The disclosure also relates to radiopharmaceutical kits comprising precursors to the radiolabeled tracers, which can be converted to the radiolabeled tracers using the processes described herein.
The present invention relates to novel solid-phase processes for the production of radiolabelled tracers, in particular for the production of
18
F-labelled compounds which may be suitable for use as Positron Emission Tomography (PET) radiotracers. The invention also comprises radiopharmaceutical kits using these novel processes.
