Description
Ferrous Chloride (CAS 7758-94-3, EC 231-843-4) is an inorganic iron salt with the formula Cl2Fe, commonly referred to as FeCl2 or iron dichloride. It carries no E-code designation and is classified within the Salts & Minerals category. It is distinct from ferric chloride (FeCl3) due to its divalent iron state.
In water treatment, FeCl2 acts as a coagulant by destabilising suspended particles, enabling their removal through flocculation and sedimentation. In textile and leather processing, it functions as a mordant and colorant, fixing dyes to fibres through coordination with metal-reactive groups. It also serves as a catalyst and antimicrobial agent in select chemical synthesis and preservation applications.
FeCl2 is supplied in technical and industrial grades, typically as beaded crystals, and is subject to REACH registration requirements for EU procurement. Buyers should confirm grade specification, iron content, and packaging format directly, as these vary by application and supplier.
