Stannous chloride is used as a source of tin in radiopharmaceutical kits. Tin reduces technetium-99m, the active radiological agent, allowing it to form a complex with phosphate-containing moeities [A32700]. These complexes localize primarily in bone (40-50%) and infracted myocardium (0.01-0.02%/g of tissue) allowing for imaging of areas of altered osteogenesis or necrotic heart tissue [FDA Label].
