ron(II) Chloride – Ferrous Chloride for Chemical Processing and Industrial Applications
Introduction
Iron(II) Chloride, also known as Ferrous Chloride, is an inorganic iron salt containing iron in the +2 oxidation state. It is used in chemical manufacturing, metal treatment, wastewater processing, and other industrial applications where a soluble ferrous iron compound is required.
Its chemical formula in anhydrous form is FeCl₂. Iron(II) Chloride is also available in hydrated forms, including the commonly encountered tetrahydrate, FeCl₂·4H₂O. Appearance, molecular weight, iron content, and other technical properties vary depending on the hydration state and product grade.

Storage and Handling
Store Iron(II) Chloride in tightly sealed, compatible containers in a cool, dry, well-ventilated area. The anhydrous material is moisture-sensitive, so protect it from humidity and unnecessary exposure to air. Use packaging and storage equipment compatible with the product's corrosive properties.
Avoid generating or inhaling dust. Wear suitable chemical-resistant gloves, protective clothing, and safety goggles or a face shield. Iron(II) Chloride may be harmful if swallowed and can cause serious eye damage. In case of eye contact, rinse cautiously with water for at least 15 minutes and seek immediate medical attention. Follow the supplier's Safety Data Sheet (SDS) for first aid, spill response, and disposal procedures.

Quality and Supply
Iron(II) Chloride should be sourced according to the required purity, hydration state, moisture limits, and intended industrial application. Buyers should review the technical data sheet, certificate of analysis, and Safety Data Sheet to verify product identity and suitability.
Depending on supplier availability, the product may be supplied in sealed containers suitable for moisture-sensitive chemicals. Confirm the grade, packaging size, documentation, and delivery requirements before placing an order.
Conclusion
Iron(II) Chloride is a useful inorganic chemical for selected chemical synthesis, metal-processing, wastewater-treatment, and laboratory applications. Its ferrous iron content makes it suitable for processes requiring iron in the +2 oxidation state. Correct identification of the anhydrous or hydrated form, appropriate storage, and safe handling are essential for reliable use.
