Procurement managers in the chemical and pharmaceutical industries constantly seek reliable sources for high-quality raw materials. 1,2-Diiodoethane (CAS 624-73-7) is one such compound, essential for specific synthetic applications. Navigating the supply landscape to secure this chemical intermediate at a competitive price requires insight into its properties, uses, and the capabilities of potential suppliers. Understanding the market, especially concerning manufacturers in China, can significantly streamline the purchasing process.

1,2-Diiodoethane is an organoiodine compound with a distinct set of physical and chemical properties. Its molecular formula C2H4I2 and molecular weight of 281.86 indicate its structure, while its appearance as dark brown crystals and a melting point of 80-82°C provide practical handling information. Crucially, its assay of ≥99.0% signifies a high level of purity, which is indispensable for its primary applications. When evaluating suppliers, checking for conformity to factory standards and clarity on analytical results is fundamental for any procurement decision.

The significance of 1,2-Diiodoethane is largely derived from its role as a precursor in the synthesis of valuable reagents such as samarium(II) iodide and ytterbium(II) iodide. These low-valent lanthanide iodides are potent reducing agents frequently employed in complex organic transformations, including carbon-carbon bond formation and stereoselective reductions. Consequently, companies involved in fine chemical synthesis, pharmaceutical R&D, and advanced materials development often require a consistent supply of this intermediate. For procurement managers, identifying suppliers who can guarantee these high-purity specifications is a priority.

When seeking to purchase 1,2-Diiodoethane, understanding the global manufacturing landscape is advantageous. China has emerged as a major hub for chemical production, offering competitive pricing and a vast array of intermediates. Engaging with established manufacturers in this region can provide access to cost-effective solutions, provided quality control and supply chain reliability are assured. It’s advisable to request quotations and review Certificates of Analysis (CoAs) from potential suppliers to verify product quality and consistency. Seeking out a manufacturer that also offers efficient packaging solutions, such as 25 kg drums, can further simplify logistics.

In summary, for procurement managers tasked with sourcing 1,2-Diiodoethane, focusing on purity (≥99.0%), application relevance (organic synthesis, SmI2/YbI2 preparation), and supplier reliability is key. Exploring partnerships with experienced manufacturers, particularly those in China known for their production capabilities, can lead to cost savings and a more secure supply chain.
