Abstract: Provided is a novel method for labeling a radionuclide such as 211 At with a high radiochemical yield under more convenient and stable conditions.
A production method of an aryl compound labeled with a radionuclide includes a step of applying a voltage to a solution A containing a radionuclide and electrolytically oxidizing the radionuclide; and a step of mixing the solution A and a solution B containing a compound S having a halogenated aryl group to substitute a halogen atom on the aryl group of the compound S with the radionuclide.
