Ammonium bromide Uses

 Ammonium bromide (cas no.12124-97-9) is used for photography in films, plates and papers;in corrosion inhibitors;in lithography and process engraving;in fireproofing of wood;  and in pharmaceutical preparations.

Ammonium bromide Production

 Ammonium bromide (cas no.12124-97-9) can  be prepared by the reaction of ammonia with iron(II) bromide or iron(III) bromide, which may be obtained by passing aqueous bromine solution over iron filings.
  2 NH3 + FeBr2 + H2O → 2 NH4Br + FeO 
It can also be prepared by the action of hydrogen bromide on ammonia as following:
   NH3 + HBr → NH4Br
