000843844 520__ $$aA fast and efficient process for the productionof the PET radionuclide 73Se was developed using 75Se as asurrogate. 75Se was separated from proton irradiated arsenictrioxide by reaction with 2,3-diaminonaphthalene to4,5-[75Se]benzopiazelenol. This compound was purifiedusing SPE column chromatography and subsequentlydecomposed with hydrogen peroxide. For further chemicalconversions [75Se]selenite was reduced to elemental[75Se]selenium by either using thiosulfate or sulfur dioxide.The recovery yield of 75Se from the target amountedto 43 %. The utility of the isolated 75Se for radiosyntheseswas demonstrated by the successful preparation of [75Se]selenomethionine.The methodology developed using 75Sewas successfully transformed to 73Se.
