For chemists and researchers engaged in the intricate world of organic synthesis, the selection of high-quality reagents is paramount. Among these essential compounds, Diiodomethane, also known by its synonym Methylene Iodide (CAS 75-11-6), stands out for its unique reactivity and versatility. This organoiodine compound is a cornerstone in various synthetic pathways, most notably the acclaimed Simmons-Smith reaction, a powerful method for cyclopropanation.

The Simmons-Smith reaction utilizes Diiodomethane in conjunction with a zinc-copper couple to effectively convert alkenes into cyclopropanes. This transformation is crucial for building complex molecular architectures found in pharmaceuticals, agrochemicals, and natural products. The controlled introduction of a methylene group (CH₂) across a carbon-carbon double bond is a foundational step in many synthetic strategies, and Diiodomethane is the key ingredient that makes this possible. Understanding how to buy Diiodomethane online from a reputable Diiodomethane supplier China is therefore essential for many research and manufacturing facilities.

Beyond its celebrated role in cyclopropanation, Diiodomethane possesses a high density, approximately 3.325 g/mL at 25°C. This physical property makes it an invaluable tool in laboratory settings for density separation techniques. It is frequently employed to determine the densities of minerals and other solid materials, aiding in identification and characterization processes. Furthermore, its high refractive index of around 1.737 positions it as a useful optical contact liquid for gemological analysis, helping to determine the refractive index and identify mineral density separations.

For procurement managers and R&D scientists, identifying a reliable manufacturer for Diiodomethane is a critical step. Sourcing from China offers competitive advantages, provided the supplier adheres to strict quality control measures. When looking for Diiodomethane for sale, prioritizing purity and consistent product specifications is key to achieving reproducible results in your experiments and production processes. The availability of high purity Diiodomethane ensures that side reactions are minimized and yields are maximized.
