What is a Copper(I) bromide (CuBr)?

Copper(I) bromide (CuBr) is an inorganic compound composed of copper and bromine, where copper exists in the +1 oxidation state. It typically appears as a white or light yellow crystalline solid and is poorly soluble in water. Copper(I) bromide plays an important role in chemical reactions as a catalyst, particularly in organic synthesis for reactions like alkylation and halogenation. It is also used in the production of copper metal and in electrochemical processes and alloy manufacturing.

The industrial production of CuBr involves the reaction of copper metal with bromine, and it can be produced using either dry or wet methods. Copper(I) bromide is chemically stable and exhibits resistance to temperature and humidity, but it can degrade in high humidity conditions. While it is generally stable, proper storage and handling are necessary to prevent deterioration or harmful exposure. Copper(I) bromide is toxic if ingested or if it comes in contact with skin, so appropriate safety precautions should be taken.
