Oxidizing agent in chemical and analytical laboratories. Reagent in redox titrations and electrochemical studies. Used in histology and biological staining techniques (e.g. Prussian blue staining). Component in photographic and blueprint processing. Employed in metal treatment and corrosion studies.

Its primary purpose is to serve as a mild oxidizing agent and analytical reagent for oxidation-reduction reactions metal ion detection staining procedures and various research and industrial processes.

Potassium hexacyanoferrate(III) commonly known as potassium ferricyanide is a orange solid water-soluble coordination compound containing iron in the 3 oxidation state. Despite containing cyanide groups it is relatively stable under normal conditions and is widely used in analytical industrial and laboratory applications.
