Stannic Iodide, chemically known as Tin(IV) Iodide (I4Sn, CAS 7790-47-8), is a compound of significant interest in the chemical industry due to its unique properties and synthesis pathways. Its distinctive red-orange color hints at its chemical nature, making it easily identifiable. For researchers and manufacturers, a thorough understanding of its synthesis and properties is essential for its effective utilization.

The synthesis of Stannic Iodide is primarily achieved through two main routes. The first involves the direct reaction between iodine and tin metal. This method is straightforward and commonly employed for laboratory-scale preparation. The second method involves the reaction of tin(IV) oxide with hydroiodic acid. Both routes are effective in producing Tin(IV) Iodide, with the choice often depending on the availability of starting materials and the desired purity of the final product. High purity grades, such as those with a metals basis assay of 99.998%, are available for demanding applications.

The physical properties of Stannic Iodide are well-documented. It appears as a red powder and has a melting point of 144°C, transitioning to a liquid state above this temperature. Its boiling point is considerably higher, at 364°C. The density of the compound is 4.47 g/mL at 25°C, and it exhibits a refractive index of 2.106. Its solubility in common organic solvents like benzene, chloroform, and ether is a key feature that facilitates its use in various chemical reactions. Crucially, it is sensitive to moisture and decomposes in water, forming hydriodic acid and tin(IV) oxide. This hydrolytic sensitivity necessitates storage in dry conditions, often under an inert atmosphere.

In terms of applications, Stannic Iodide serves as a vital chemical reagent. It is widely used in organic synthesis to facilitate specific chemical transformations. Its role in analytical chemistry is also significant, contributing to precise measurements and qualitative analyses. The compound is also used in the preparation of tin-based oxides and in the formulation of certain specialty chemicals. The availability of this compound from manufacturers like NINGBO INNO PHARMCHEM CO.,LTD. ensures that researchers and industries have access to a reliable source for their needs, supporting advancements in chemical research and industrial processes. The consistent quality and purity of Stannic Iodide are critical for reproducible results in any chemical application.
