Ammonium ferric sulphate has a variety of applications in chemical and biological sectors. This compound is acidic and toxic to many microbes. It is used in adiabatic refrigeration equipment, biochemical analysis and organic synthesis. It acts as a weak oxidizing agent, which can be reduced to ferrous ammonium sulphate, Mohr's salt. Ferric alum finds applications in waste water treatment, tanning, production of dyestuffs, and as an etching agent in the production of electronic components. The dodecahydrate salt can be used as a catalyst to synthesize isoamyl acetate from acetic acid and isoamyl alcohol. This reagent is suitable for industrial synthesis of products and research applications.
