Product Description：Diiodomethane or methylene iodide, commonly abbreviated "MI", is a liquid organoiodine compound insoluble in water, soluble in ether and alcohol. It has a relatively high refractive index of 1.741, and a surface tension of 0.0508 N·m?1. Diiodomethane is a colorless liquid, however, it decomposes upon exposure to light liberating iodine, which colours samples brownish.
With its high specific gravity, diiodomethane is used in the determination of the density of mineral and other solid samples. It has been used for separation of minerals. It is also used as a contact liquid for refractometers. Diiodomethane is a reagent in the Simmons-Smith reaction, serving as a source of methylene.
