Diiodomethane (CAS 75-11-6), also known as Methylene Iodide, is a chemical compound that bridges multiple disciplines within chemistry and materials science. Its unique properties, including reactivity in organic synthesis and physical characteristics like high density and refractive index, make it a versatile and essential reagent for a wide range of applications.

In the realm of organic synthesis, Diiodomethane is most celebrated for its participation in the Simmons-Smith reaction. This classic organic transformation allows for the efficient synthesis of cyclopropane rings, which are vital building blocks in the creation of complex molecules such as pharmaceuticals, fragrances, and advanced materials. The controlled introduction of a methylene carbene equivalent using Diiodomethane is a testament to its synthetic utility. For chemists aiming to excel in synthetic organic chemistry, understanding where to buy Diiodomethane of sufficient purity is crucial.

Beyond its role in creating new carbon-carbon bonds, Diiodomethane’s physical properties are equally significant. Its remarkable density, around 3.325 g/mL, makes it an ideal medium for density separation techniques. In geological and mineralogical studies, it is used to separate minerals of varying densities, facilitating sample analysis and purification. Furthermore, its high refractive index (n D ≈ 1.737) positions it as a valuable optical contact liquid for determining the refractive indices of transparent solids, aiding in material identification and quality control.
