A simplified, robust protocol for [18F]fluoride elution under mild conditions to enhance late-stage aromatic radiofluorinations

Scientific Reports
Direct radiofluorination of base-sensitive PET precursors is challenging due to the harsh reaction conditions of traditional fluorine-18 radiochemistry. In particular, the presence of inorganic bases with a relatively high conjugate pK a (e.g. K2CO3) and
