Strontium diiodide(CAS: 10476-86-5)

Strontium diiodide (SrI2) is a white crystalline solid with a molecular weight of approximately 336.43 g/mol. It has a high solubility in common organic solvents such as acetone and dimethylformamide. Chemically, it is relatively stable but can react with strong acids to form iodine and strontium salts. It is insoluble in water but slightly soluble in dilute nitric acid.

Strontium diiodide can be synthesized by reacting strontium oxide or strontium carbonate with iodine. The reaction can be carried out in a stream of iodine vapor at high temperatures, typically above 500°C. Alternatively, it can be produced by the direct reaction of strontium metal with iodine. The reaction is exothermic and requires careful control to avoid decomposition of the product.

Strontium diiodide finds applications in various industries. It is used in the production of phosphors for x-ray screens, as a component in some semiconductor devices, and as a precursor in the synthesis of other strontium compounds. It is also utilized in the field of analytical chemistry for spectroscopic studies and as a reagent in certain organic reactions.

When handling strontium diiodide, it is important to wear appropriate personal protective equipment (PPE) including gloves, safety goggles, and a lab coat. It should be stored in a well-ventilated area away from moisture and strong acids. In case of a spill, it should be handled carefully to prevent inhalation or skin contact. Always refer to the Material Safety Data Sheet (MSDS) for detailed safety information and emergency procedures.
