Special Hazards of Combustion Products: Material decomposes into N 2 and HBr or Br 2 under extreme temperatures. | [Description]
Ammonium bromide is soluble in water and alcohol and is not particularly hazardous under normal conditions. | [Chemical Properties]
white crystals | [Physical properties]
Colorless rhombic crystal; odor of ammonia; sublimes at 60°C; very soluble in cold water; decomposes in hot water; slightly soluble in alcohol; insoluble in acetone. | [Definition]
ChEBI: An ammonium salt composed of ammonium and bromide ions in a 1:1 ratio. | [Flammability and Explosibility]
Nonflammable | [Purification Methods]
It crystallises from 95% EtOH and is slightly hygroscopic. |
