Are Sodium Ferrocyanide and Sodium Hexacyanoferrate(II) the same salt?

Yes. Sodium ferrocyanide and sodium hexacyanoferrate(II) name the same ferrocyanide salt; CAS 13601-19-9 identifies the anhydrous form. The decahydrate is CAS 14434-22-1. Neither is sodium ferricyanide or free cyanide. Confirm the exact hydrate and assay basis in the quotation.

What is Sodium Ferrocyanide used for?

Sodium ferrocyanide is used as a precursor to iron blue pigments and in selected industrial processes. Anti-caking use depends on local approval and the offered grade. State the intended application; do not infer suitability from the CAS number alone.

Which specifications should be agreed for industrial Sodium Ferrocyanide?

Specify assay and reporting basis, water or hydrate content, free cyanide where required, chloride, sulfate, insoluble matter, iron and relevant heavy metals. Technical and regulated grades are not interchangeable, so state the required grade and test methods.

What safety and regulatory points apply to Sodium Ferrocyanide?

Sodium ferrocyanide is a coordinated ferrocyanide salt, not free cyanide or ferricyanide. Contact with acids can release hydrogen cyanide. Check the current supplier SDS for the offered anhydrous or hydrated form, transport route and destination; do not assign UN 1588 to this product by name.

What hydrate and physical data should be confirmed for Sodium Ferrocyanide?

Sodium ferrocyanide can be offered in anhydrous or hydrated form. The decahydrate has a separate identifier, CAS 14434-22-1. State the hydrate, assay calculation basis, water content, form and destination; verify density, solubility and storage data against the exact offered specification.

Sodium Ferrocyanide CAS 13601-19-9

Sodium Ferrocyanide, CAS 13601-19-9, is also known as yellow prussiate of soda or sodium hexacyanoferrate(II). It is an inorganic coordination compound used in salt processing and as a raw material for pigments, tanning, smelting and metal treatment. Confirm the hydrate state, assay basis, impurity limits, packaging and documentation before ordering.
