Efficient and selective labelling of the CFC alternative, 1,1,1,2-tetrafluoroethane, with 18F in the 1-position
Abstract
Treatment of trifluoroethylene with cyclotron-produced [18F]fluoride, in the presence of potassium carbonate-aminopolyether 2.2.2, labels 1,1,1,2-tetrafluoroethane efficiently and selectively in the 1-position.
