Copper bromide (CuBr₂ ) is an inorganic compound that is highly soluble in water, alcohol, and acetone, but insoluble in ether and liquid ammonia. It forms a deep green solution when dissolved in water, alcohol, or acetone, due to the presence of the CuBr2 ion.

In terms of its physical characteristics, it is often presented as a white or light brown crystalline solid under normal conditions. However, it can turn blue-green when exposed to moist air because of hydrolysis.

Applications of Copper Bromide

Copper bromide has a variety of applications, particularly in the field of chemistry. It is often used as a catalyst in organic synthesis and is part of a group of reagents used in Sandmeyer reactions. Furthermore, it is also used in the manufacturing of photographic developer solutions and in the creation of bright blue-green pigments.

In the field of photonics and optics, copper bromide lasers are known for their use in medical applications. These lasers emit high-intensity green-yellow light that is efficiently absorbed by hemoglobin, making them ideal for treatments like dermatological procedures and vascular lesions.
