Chromium(II) Chloride (CAS 10049-05-5) is a significant inorganic compound with diverse applications, particularly in organic synthesis and catalysis. As a B2B procurement professional or a research scientist, understanding its characteristics, practical uses, and the best channels to purchase it is vital for successful operations. This article provides a detailed overview of Chromium(II) Chloride, catering to the needs of industry professionals.

The chemical, with the molecular formula Cl2Cr, is typically encountered as a pale green to gray powder, boasting a high assay, often around 98%. This purity is critical for its effectiveness in demanding chemical processes. Its physical and chemical properties make it a versatile reagent. For example, it's known to convert terminal olefins into trans iodocyclopropane in high yields, a useful reaction in the synthesis of complex molecules. Furthermore, it assists in controlling the condensation of aldehydes with substituted chloroolefins, offering chemists a precise tool for molecular construction.

In the realm of catalysis, Chromium(II) Chloride functions as a high-activity pre-catalyst for ethylene oligomerization. This application is particularly impactful in the petrochemical industry, where efficient conversion of ethylene into longer-chain hydrocarbons is essential for producing various polymers and chemical feedstocks. Manufacturers looking to optimize their production processes often seek to buy Chromium(II) Chloride for its catalytic efficiency.

Beyond these primary applications, Chromium(II) Chloride is used in the preparation of other chromium complexes and finely divided intermetallic compounds. These materials can possess specialized thermoelectric, magnetic, and antioxidant properties, finding utility in advanced materials science. The demand for high-purity Chromium(II) Chloride from reliable sources underscores its importance in these cutting-edge fields.

For procurement professionals, sourcing Chromium(II) Chloride involves understanding its CAS number (10049-05-5) and identifying trusted manufacturers and suppliers. China is a significant hub for the production of such specialty chemicals, offering competitive pricing and substantial manufacturing capacities. When you intend to buy Chromium(II) Chloride, it is advisable to request detailed specifications, including assay and any trace impurities, alongside a competitive price quote. Factors like packaging and storage requirements (it is hygroscopic) are also important considerations provided by suppliers. Ensuring a stable supply chain from a dependable manufacturer or supplier is key to maintaining consistent production and research timelines.
