FeCl2
metal· FeCl2
Iron(II) chloride (FeCl₂) is an inorganic salt compound consisting of iron in the +2 oxidation state bonded to chloride ions, typically available as a hydrated crystalline solid. While not a structural metal itself, FeCl₂ serves as a precursor material and chemical reagent in industrial processes, notably in water treatment, metal surface preparation, and synthesis of iron-containing compounds. Engineers select FeCl₂ for applications requiring controlled iron chemistry, corrosion inhibition through ferrous ion chemistry, or as a starting material for specialized coatings and catalysts, rather than for load-bearing structural purposes.

Export Control
RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
