Bromine azide is an explosive inorganic compound with the formula BrN₃. It has been described as a crystal or a red liquid at room temperature. It is highly sensitive to small variations in temperature and pressure, with explosions occurring at Δp (pressure change) ≥ 0.05 Torr upon crystallization, thus extreme caution must be observed when working with this chemical.
