Sodium ferrocyanide(Cas 13601-19-9) Usage


Sodium ferrocyanide is an odorless yellow solid and the sodium salt of the coordination compound [Fe(CN)6]4?. Also known as yellow prussiate of soda in its hydrous form (Na4Fe(CN)6 ? 10H2O), it is a yellow crystalline solid with solubility in water and insolubility in alcohol. The yellow color is attributed to the ferrocyanide anion. Despite containing cyanide ligands, sodium ferrocyanide has low toxicity, with an acceptable daily intake of 0–0.025 mg/kg body weight. It is considered less toxic than many other cyanide salts.


Sodium ferrocyanide is produced industrially from hydrogen cyanide, ferrous chloride, and calcium hydroxide, the combination of which affords Ca2[Fe(CN)6] ? 11H2O. A solution of this salt is then treated with sodium salts to precipitate the mixed calcium-sodium salt CaNa2[Fe(CN)6], which in turn is treated with sodium carbonate to give the tetrasodium salt.


Hygroscopic, -20°C Freezer, Under inert atmosphere


Sodium ferrocyanide is a coordination compound of iron. The cyanide ligands are tightly bound to the iron, so it is not as toxic as simple inorganic cyanide salts. However, this compound can release hydrogen cyanide gas upon reaction with acids.


Sodium ferrocyanide is a yellow crystalline salt Na4Fe(CN)6 similar to potassium ferrocyanide and used in making iron blue pigments, blueprint paper, and dyes — Called also yellow prussiate of soda

Chemical Properties



Toxicity: Sodium ferrocyanide is less toxic than many other cyanide salts, posing a low risk of releasing free cyanide.

Hydrogen Cyanide Production: While generally low in toxicity, the addition of an acid to sodium ferrocyanide can produce hydrogen cyanide gas, which is toxic.

Sodium Ion Batteries: Sodium hexacyanoferrate(II) decahydrate, a form of sodium ferrocyanide, is being investigated as a potential cathode material for sodium ion batteries.

Manufacture: Used in the manufacture of sodium ferricyanide, blue pigments, and blueprint paper.

Air & Water Reactions

Water soluble.

Reactivity Profile

Sodium ferrocyanide has weak oxidizing or reducing powers. Redox reactions can however still occur. The majority of compounds in this class are slightly soluble or insoluble in water. If soluble in water, then the solutions are usually neither strongly acidic nor strongly basic. These compounds are not water-reactive.

Health Hazard

None recorded.

Flammability and Explosibility


Safety Profile

When heated to decomposition emits toxic fumes of CN-.

Purification Methods

Crystallise it from hot water (0.7mL/g), until free of ferricyanide as shown by the absence of formation of Prussian Blue colour with ferrous sulfate solution.
