3-[18F]Fluoropropyl-, 4-[18F]fluorobenzyl-triphenylphosphonium and 4-[18F]fluorobenzyltris-4-dimethylaminophenylphosphonium cations were synthesized in multi-step reactions from no carrier added (nca) [18F]fluoride. The time for synthesis, purification, and formulation was 56, 82, and 79 min with an average radiochemical yield of 12, 6 and 15%, respectively (not corrected for decay). The average specific radioactivity for the three radiolabeled compounds was 14.9 GB q/µmole (403 mCi/µmole) at end of synthesis (EOS). Copyright © 2004 John Wiley & Sons, Ltd.
