Iron(II) chloride tetrahydrate is used as a reducing agent in metallurgy, in pharmaceutical preparations, as a mordant in dyeing and in sewage treatment.
Ferrous chloride has a kind of niche application.
During the laboratory synthesis of iron complexes, ferrous chloride acts as a reducing flocculating agent in waste water treatment, particularly for wastes containing chromate.
It is the precursor to hydrated iron(III) oxides that are magnetic pigments.
Ferrous chloride is employed as a reducing agent in many organic synthesis reactions.
