Product Name:Sodium iodide
English Name:Sodium iodide
CAS No.:7681-82-5
Aliases:Sodium monoiodide
Molecular Formula:NaI
Physical Properties:White cubic crystals or granular powder, odorless, salty and slightly bitter taste. Melting point 661℃, boiling point 1304℃, relative density 3.667 (25℃). Readily soluble in water, with solubility of 158.7g/100mL water at 0℃, 190.3g at 30℃, and 302g at 100℃. Also soluble in methanol, ethanol, glycerol and liquid ammonia. Hygroscopic in air, decomposes upon exposure to light or air with liberation of free iodine causing yellowing of crystals. Forms pentahydrate and dihydrate with transition temperatures of -13.5℃ and 65℃ respectively.
Uses:Used as raw material for manufacturing inorganic and organic iodides. In pharmaceutical applications, it serves as an expectorant, diuretic, thyroid goiter preventive agent, and X-ray contrast medium for cystography and retrograde urography. Also used as photographic film sensitizer, iodine solubilizer, analytical reagent, and for microdetermination of cesium, platinum and thallium.
