-In addition to radionuclidic purity another term, //radiochemical purity// is important, particularly in labelling of organic molecules, for radiopharmaceutical purpose for example. Radiochemically pure compounds are the desired compounds containing the radionuclide or the compounds containing the radionuclide in a desired position. In, for example, <sup>18</sup>F-labelled radiopharmaceutical 2-FDG (2-deoxy-2-[<sup>18</sup>F]fluoro-D-g1ucose) product the radiochemically impure compounds are those where the <sup>18</sup>F-label is somewhere else than in 2-deoxy position or other <sup>18</sup>F-labelled compounds, such as tetra-acetyl-2-[<sup>18</sup>F]FDG.+In addition to radionuclidic purity another term, //radiochemical purity// is important, particularly in labelling of organic molecules, for radiopharmaceutical purpose for example.
