An alternative procedure to produce 4-dihydroxyboryl-2-[18F]fluorophenylalanine ([18F]FBPA) for positron emission tomography studies in boron neutron capture therapy is described. Relatively high-specific activity electrophilic radiofluorine is produced using a post-target conversion of [18F]F– to [18F]F2. Liquid chromatography with mass spectrometric detection is used to estimate the specific radioactivity of [18F]FBPA and to verify the quality control for chemical identity of the target compound. [18F]FBPA produced according to this method fulfilled the pharmaceutical quality requirements for an injection in patients. Copyright © 2002 John Wiley & Sons, Ltd.
