Ammonium Iron(II) Sulfate Hexahydrate (Mohr’s Salt)(CAS: 7783-85-9)

Ammonium Iron(II) Sulfate Hexahydrate, also known as Mohr’s Salt, is a crystalline double salt with the chemical formula (NH4)2Fe(SO4)2·6H2O. It is commonly used as a stable source of ferrous ions (Fe²⁺) in chemical reactions. The compound is blue-green in color, highly soluble in water, and contains six water molecules per formula unit. CAS 7783-85-9 identifies this specific hydrate form.

Ammonium Iron(II) Sulfate Hexahydrate (Mohr’s Salt) is widely used in laboratories for qualitative and quantitative analysis, such as in titration experiments. It serves as a precursor in the synthesis of other iron compounds and is employed in electroplating, dyeing, and as a catalyst. Additionally, it is used in pharmaceuticals for iron supplementation and in food industry applications for nutrient fortification. Its stability and solubility make it a valuable reagent in chemical research.

Ammonium Iron(II) Sulfate Hexahydrate (Mohr’s Salt) is generally considered safe when handled properly. However, it may cause mild skin or eye irritation. Safety guidelines recommend using gloves, safety goggles, and ensuring adequate ventilation during handling. While it is not classified as highly toxic, adherence to standard chemical safety protocols is essential to minimize risks. The compound complies with regulatory safety standards for laboratory and industrial use.

Ammonium Iron(II) Sulfate Hexahydrate (Mohr’s Salt) should be stored in a cool, dry place away from moisture and direct light. It requires airtight, moisture-proof containers to maintain its crystalline structure and prevent decomposition. Storage conditions should be below 25°C to ensure stability. Avoid exposure to high humidity or heat, and keep it in a well-ventilated area to prevent inhalation of dust. Proper labeling is also crucial for safe handling.
