[AlCl3(BnMe2-tacn)] – a new metal chelate scaffold for radiofluorination by Cl/F exchange
Radiofluorination of a 2.63 μM solution (pH 4, NaOAc buffer) of [AlCl3(BnMe2-tacn)] via treatment with 2.99 mol. equiv. of [19F]KF doped with cyclotron-produced [18F]F− target water, with heating to 80–100 °C for 1 h, gives up to 24% 18F incorporation. SPE purification of the [Al19F218F(BnMe2-tacn)] radio-product gives >99% RCP, with excellent stability (>99% RCP after 3 h).
