Prussian blue is described as a deep blue pigment that is produced when the oxidation of ferrous ferrocyanide salts occurs. It contains ferric hexacyanoferrate(II) in a cubic lattice crystal structure. It is insoluble in water but also tends to form a colloid thus can exist in either colloidal or water-soluble form, and an insoluble form. It is orally administered for clinical purposes to be used as an antidote for certain kinds of heavy metal poisoning, including thallium and radioactive isotopes of caesium. Prussian blue is included in the World Health Organization Model List of Essential Medicines as a specific antidote used in poisonings to provide symptomatic and supportive treatment. It was also administered in individuals exposed to 137-Cs+ during Goiânia accident, one of the worst radioactive contamination incidents that occured in Brazil, 1983. Its therapeutic use is listed as antidotes. The directory classifies it as a commercial API with a mineral/inorganic source/manufacturing origin. Other names for this substance include Prussian blue insoluble, Ferrocin, Preussischblau, Berliner Blau and Ferrotsin. Its PubChem CID is 2724251.
