CAS 13601-19-9 corresponds to anhydrous sodium ferrocyanide (commonly known as sodium ferrocyanide), with the molecular formula Na ₄ [Fe (CN) ₆] and a molecular weight of 303.91. It is a lemon yellow crystal that is easily soluble in water and is mainly used as a salt anti caking agent and industrial pigment raw material.

Basic Information
-Chinese name: Sodium ferrocyanide (anhydrous); Nicknames: Sodium ferrocyanide, Sodium hexacyanoferrate (II)
-English name: Sodium ferrocyanide (anhydrous)
-Molecular formula: Na ₄ [Fe (CN) ₆]
-Molecular weight: 303.91
-EINECS number: 237-081-9
-Appearance: Lemon yellow monoclinic crystal with angular or needle shaped crystals/powder
-Solubility: soluble in water, almost insoluble in organic solvents such as ethanol
-Relative density: approximately 1.458

main purpose
1. Food additive: used as an anti caking agent in table salt to prevent clumping (limited to ≤ 10 mg/kg table salt in China, calculated as ferrocyanide).
2. Industrial pigments: Manufacturing Prussian blue and other blue pigments for use in paints, inks, and sun dried drawings.
3. Other industries: steel carburizing, tanning, metal corrosion prevention, pharmaceutical iron removal agents, and preparation of red blood salt raw materials.

Safety and Attention
-Toxicity: structurally stable, ADI value of 0-0.25 mg/kg body weight (FAO/WHO); Under normal usage, it is non-toxic, but when exposed to strong acids, it can release highly toxic hydrogen cyanide gas.
-Storage: Store in a cool and dry place to avoid moisture, weathering, or high-temperature decomposition.

Note: This CAS number specifically refers to anhydrous substances; Its common decahydrate (Na ₄ [Fe (CN) ₆] · 10H ₂ O) has a CAS number of 14434-22-1.
