Product details:

Uses:

It is used as effective catalyst for tetrahydropyranylation of alcohols.  It can also be used in combination with palladium in catalytic synthesis of 3-haloindoles through annulation process.  It is widely used in the synthesis of organic fine chemicals.  The compound is widely used in the synthesis of organic compounds.  It is also useful for copper-mediated coupling reactions.  A silica gel support copper bromide hexa methyltriethylenetetramine complex has shown useful application for the atom transfer radical polymerization of methyl methacrylate in toluene.Copper bromide is also known as cupric bromide, this substance was made by double decomposition when mixing aqueous solutions of copper sulfate and potassium bromide.  This greenish blue solution was used as the bleaching step for intensifying collodion and gelatin negatives.It is prepared pyrometallurgically with copper metal and elemental bromine in a process similar to that for copper(I) chloride.  It can also be produced by the reduction of copper(II) sulfate solutions in the presence of sodium bromide using metallic copper or sulfite as the reducing agent.  Copper(I) bromide is used as a polymerization catalyst in organic reactions. As catalyst for organic reactions.
