Product Name:Zinc iodide
English Name:Zinc iodide
CAS No.:10139-47-6
Aliases:Zinc diiodide, Zinc(II) iodide
Molecular Formula:ZnI₂
Physical Properties:White or off-white crystalline powder, hygroscopic. Freely soluble in water, ethanol, ether and ammonia water; aqueous solution is acidic. Melting point approximately 446°C, boiling point approximately 624°C, density approximately 4.74 g/mL. Decomposes upon exposure to moisture in air; store in a sealed container away from light.
Uses:Zinc iodide is used as a catalyst in organic synthesis, particularly in esterification, addition and condensation reactions. In analytical chemistry, it serves as an indicator or reagent in iodometric titrations. It is also employed as an intermediate in pharmaceutical synthesis, in photosensitive materials, and as a precursor for preparing other zinc salts or iodides.
