Soluble in hydrogen bromide, hydrochloric acid, and ammonium hydroxide. Slightly soluble in water. Insoluble in acetone.


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.


It is a stable, but air or light sensitive chemical compound. Keep container in a cool, well-ventilated area. Do not store above 35°C (95°F) and keep away from incompatibles such as oxidizing agents, alkalis.
