It is a white or transparent solid with melting point at 636 °C that readily dissolves in water.

Its bulk crystals have the cubic CsCl structure, but the structure changes to the rocksalt type in nanometer-thin film grown on mica, LiF, KBr or NaCl substrates.

Caesium bromide is sometimes used in optics as a beamsplitter component in wide-band spectrophotometers.
