Potassium Ferrocyanide, Grade : Pharma Grade, Purity : 99.5%

Potassium Ferrocyanide (K₄[Fe(CN)₆]) is a light yellow, odorless crystalline compound used in industries and laboratories. It’s water-soluble and stable under normal conditions. Commonly used as an anti-caking agent in salt, it also plays roles in pigment production, steel hardening, and chemical analysis—especially for detecting iron by forming Prussian Blue. Despite containing cyanide groups, it’s considered low in toxicity when handled properly.
