Iron(III) chloride hexahydrate is used to prepare organically templated iron phosphates. It is used for sewerage treatment of industrial wastes, chloride hydrometallurgy (Silgarin process for the production of silicon), drinking water production, production of precursors for polyvinyl chloride (PVC) and copper-based metals in printed circuit boards. It plays an important role in photoengraving and photography as an etching agent. It is useful as a mordant in dyeing and printing textiles. It is useful in the detection of phenols and phenolic derivatives; gamma-hydroxybutyric acids and also in the Trinder spot test for detecting salicylic acids.


Hygroscopic. Keep the container tightly closed in a dry and well-ventilated place. Incompatible with strong oxidizing agents, sodium and sodium oxides and potassium.
