Potassium Ferrocyanide Extra Pure
Original price was: $ 16.79.$ 16.67Current price is: $ 16.67.
Potassium Ferrocyanide Extra Pure is a pale yellow crystalline salt known for its stability and low toxicity in pure form. It is widely used in analytical chemistry for the detection of metal ions, particularly in the formation of Prussian blue with iron. In industrial settings, it serves roles in pigment production, electroplating, and as an anti-caking agent in salt. Despite the presence of “cyanide” in its name, it is non-toxic under normal conditions due to its tightly bound cyanide groups. This compound should be handled with care and stored in sealed containers in a cool, dry area, away from acids and oxidizing agents.
