Ammonium bromide, 99.0+%

Ammonium bromide, NH4Br, is the ammonium salt of hydrobromic acid. The chemical crystallizes in colorless prisms, possessing a saline taste; it sublimes on heating and is easily soluble in water. On exposure to air it gradually assumes a yellow color because of the oxidation of traces of bromide (Br-) to bromine (Br2).

Ammonium bromide is used for photography in films, plates and papers, in fireproofing of wood, in lithography and process engraving, in corrosion inhibitors and in pharmaceutical preparations.
