Sodium Ferrocynide (CAS 13601-19-9) is a yellow crystalline salt of the hexacyanoferrate family, also known as Yellow Prussiate of Soda, supplied in Food Grade and Technical Grade for use as an anticaking agent in table and de-icing salts, as a raw material in pigment production, and in mining flotation. It is most recognized for its role as a highly effective anticaking agent in table salt and industrial salts.
The compound is chemically stable and possesses low toxicity, despite the presence of cyanide groups, as they are strongly bound to the iron atom. This stability makes it a safe and reliable additive for maintaining the flowability of powdered products over long storage periods.
In the industrial sector, it is used in the production of pigments and as an additive in high-performance coatings. Its high purity and consistent crystal structure ensure optimal performance in both culinary and heavy-duty manufacturing applications.
