The synthesis and properties of polymer oxidizing agent which is suitable for halogen radiolabeling in a high-speed, no-carrier-added solid-phase labeling method and its reactor are described. An electrified rhodamine and cholesterol were radiolabeled by the method, and their products were identified. The radiochem. purity of each radiolabeled compound was >95% and radioactive recovery ratio was >96%. It achieved high-speed labeling of the halogenated radiopharmaceuticals as the whole procedure was completed in 5 min. The solid-phase labeling method for the substance that can form organomercury compound is discussed.
