Introduction to Sodium Ferrocyanide: The Versatile Chemical Compound Sodium ferrocyanide, chemically known as sodium hexacyanoferrate(II) with formula Na₄[Fe(CN)₆] and CAS numbers 13601-19-9 (anhydrous) and 14434-22-1 (decahydrate), is a yellow crystalline compound that serves critical functions across multiple industries . Despite containing cyanide groups, this coordination compound is considered relatively non-toxic due to the strong binding between iron and cyanide ions, which prevents the release of free cyanide under normal conditions . Commonly known as yellow prussiate of soda in its decahydrate form (Na₄Fe(CN)₆·10H₂O), this versatile chemical exhibits excellent water solubility and stability under normal conditions, making it indispensable for food processing, pigment manufacturing, pharmaceutical applications, and industrial processes .
