Popis: The fastest and most reliable preparation of radiolabeled 5-iodo-2′-deoxyuridine ([ 123/125/131 I]IUdR) is accomplished by iododemetallation. We describe a series of improvements to a previously published synthesis of radiolabeled IUdR by demercuration whereby [ 123/125/131 I]IUdR is synthesized instantly following the incubation of an aqueous solution of the chloromercury precursor with Na 123/125/131 I in the presence of Iodogen. The total procedure is completed in 5 min and does not require purification. Mercury content is low and HPLC indicates the total transformation of iodide into IUdR with no detectable UV-absorbing by-products.
