Abstract:
The hexachlorotechnetate reagent has been used to synthesize lipophilic complexes of technetium-99m with polydentate ligands, using ligand exchange reactions and acetonitrile as an aprotic solvent. The complexes isolated were partially characterized by chromatographic (paper and HPLC) and electrophoretic methods. Preliminary data on biodistribution studies, carried out in rabbits, are also presented. This work documents that the hexachlorotechnetate reagent is a suitable intermediate for the rapid synthesis of new lipophilic complexes of technetium-99m.
