3-[18F]Fluoropropyl-, 4-[18F]fluorobenzyl- triphenylphosphonium and 4-[18F]fluorobenzyltris-4- dimethylaminophenylphosphonium cations were synthesized in multistep 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).
