1. Stannous pyrophosphate is primarily used as a diagnostic aid in nuclear medicine, where Stannous pyrophosphate is formulated with Technetium-99m for skeletal imaging, cardiac imaging to detect acute myocardial infarction, and blood pool imaging to detect gastrointestinal bleeding .
2. Stannous pyrophosphate is used as an oral care agent in dental preparations, including caries-preventing toothpaste formulations .
3. Stannous pyrophosphate is also utilized in industrial applications such as electrical tinplating and as a specialty chemical for research purposes .
Packed in 1kg aluminum foil bag / fluorine bottle, 10kg aluminum cans / cardboard box, 25kg cardboard barrel / woven bag / plastic.
1. Stannous pyrophosphate is a synthetic inorganic compound produced by thermal dehydration of stannous hydrogen phosphate, or by reacting disodium pyrophosphate (Na₂H₂P₂O₇) with stannous chloride (SnCl₂) .
2. Stannous pyrophosphate is also synthesized by reacting pyrophosphoric acid with stannous chloride, with the synthesis methods dating back to 1926 and refined through patents including US 3401012 (1968) .
3. Stannous pyrophosphate is manufactured as a sterile lyophilized powder for pharmaceutical use, where Stannous pyrophosphate is compounded by mixing sodium pyrophosphate and stannous chloride under a nitrogen atmosphere with pH adjustment using hydrochloric acid .
1. Stannous pyrophosphate is classified with GHS Warning, with hazard statements H315 (causes skin irritation), H319 (causes serious eye irritation), H335 (may cause respiratory irritation), and H303 (may be harmful if swallowed) .
2. When handling Stannous pyrophosphate, wear protective gloves, safety glasses with side-shields, impervious clothing, and use adequate ventilation to avoid breathing dust .
3. Stannous pyrophosphate has an NFPA health rating of 1, meaning Stannous pyrophosphate would cause irritation with only minor residual injury, and Stannous pyrophosphate is not flammable under typical fire conditions (NFPA Fire rating 0) .
1. Store Stannous pyrophosphate in a tightly closed container in a cool, dry, well-ventilated place, with storage temperatures recommended at 2-8°C (refrigerated) for optimal stability .
2. Store Stannous pyrophosphate away from incompatible materials including strong acids, carbon dioxide, and acid anhydrides, as Stannous pyrophosphate is stable under recommended storage conditions .
3. When kept dry and tightly closed in original packaging at room temperature, Stannous pyrophosphate has a shelf life of at least 2 years, and decomposition will not occur if Stannous pyrophosphate is used and stored according to specifications .
