[{"from": "human", "value": "Could you give me a brief overview of this molecule? [Cl-1].[Cl-1].[Sn+2]"}, {"from": "gpt", "value": "The molecule 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. 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."}]
