Home COMPANY PRODUCTS MARKETS CHALLENGE US Copper (I) iodide optimised for use in life sciences, polymer additive, electronics, and food and feed applications Products Basic copper carbonate Calcium hydroxystannate Calcium stannate Copper (I) iodide Copper (II) nitrate Doped tungsten oxides DURAGUARD S100 William Blythe manufactures copper (I) iodide to a rigorous standard, eliminating impurities that can lead to severe discolouration. Copper iodide has poor solubility in water and limited solubility in 50w% potassium iodide solutions. As a result, it can be used as a carrier of iodine where non-water solubility is required in biochemical pathways. William Blythe’s copper (I) iodide is also used in conjunction with potassium iodide to counteract the destructive effects of heat and light on polyamides, preventing discolouration and preserving the mechanical properties of polyamides (e.g. Nylon 6 and Nylon 66) in technical and engineering applications. Chemical name Copper (I) iodide Copper iodide Chemical formula CuI Molecular weight 190.45 C.A.S. number 7681-65-4 Applications William Blythe’s copper (I) iodide is ideal for use in applications such as: Life Science Reagents Reagent in the coupling of functional groups to aromatic molecules in fine chemical synthesis Sandmeyer, Finkelstein and Sonagashira reactions. Polymer Additives Heat and light stabiliser in engineering polyamides, in conjunction with potassium iodide. Electronic Chemicals Cathode material in salt water activated batteries. Food & Feed Additives Feed additive to counter iodine deficiency in animals. Product Forms William Blythe’s copper (I) iodide is available as a free-flowing white powder and masterbatches.
