Tin Tetraiodide, also recognized as Tin(IV) Iodide or I4Sn (CAS 7790-47-8), is a chemical compound that demands specific knowledge regarding its properties, handling, and procurement to ensure optimal and safe usage. This inorganic compound, appearing as a red powder, is a key component in various chemical processes and research endeavors.

The physical and chemical properties of Tin Tetraiodide are critical for its application. With a melting point around 144°C and a boiling point of 364°C, it exhibits distinct thermal behavior. Its density is 4.47 g/mL at 25°C. A notable characteristic is its solubility in organic solvents such as alcohol, benzene, chloroform, and ether, which dictates its use in non-aqueous reaction systems. However, its sensitivity to moisture is a key factor; it decomposes upon contact with water, yielding hydriodic acid and tin(IV) oxide. This necessitates anhydrous conditions for storage and handling, often requiring desiccators or inert atmosphere packaging. The purity of the compound, frequently specified as a percentage assay (e.g., 99.5% min or 99.998% metals basis), directly impacts its performance in sensitive applications.

Safe handling of Tin Tetraiodide is paramount. Due to its reactivity with moisture and potential to release toxic fumes when heated to decomposition, appropriate personal protective equipment (PPE) such as gloves, eye protection, and respiratory protection should be used. Work should be conducted in a well-ventilated area or fume hood. Proper storage in tightly sealed containers, away from moisture and incompatible substances, is essential to maintain its integrity and prevent hazardous reactions. Understanding the safety data sheets (SDS) is crucial before commencing any work with this chemical.

When procuring Tin Tetraiodide, it is important to consider the supplier's reliability and the product's specifications. Reputable suppliers, such as NINGBO INNO PHARMCHEM CO.,LTD., provide detailed product information, including purity levels, CAS numbers, and safety data. Ensuring the product meets the required quality standards for your specific application is vital, whether it's for intricate organic synthesis, analytical testing, or material preparation. Bulk procurement options are often available for industrial users, with pricing and minimum order quantities varying by supplier.

By understanding the properties, adopting safe handling procedures, and selecting a reliable procurement partner, researchers and industrial professionals can effectively leverage the capabilities of Tin Tetraiodide (I4Sn) in their work, contributing to advancements in chemistry and material science.
