Zinc bromide (MF: ZnBr₂, MW: 225.217) is an inorganic metal bromide formed by zinc and bromine. It is a white, hygroscopic crystalline powder characterized by high density, high water solubility, and strong Lewis acidity. Widely used in oil and gas drilling, battery electrolytes, and organic synthesis catalysts, it is an important inorganic chemical raw material.
