Biological grade phytic acid (inositol hexaphosphate, cyclohexanol phosphate) Molecular formula: C6H18O24P6 Molecular weight: 660.08 Physical and chemical properties: Phytic acid is a light yellow viscous liquid that is easily soluble in water, ethanol, and acetone, slightly soluble in anhydrous ethanol and methanol, and almost insoluble in ether, benzene, and chloroform. Oral administration of LD504942mg/kg to mice results in a semi lethal dose, which is less toxic than LD504000mg/kg of salt. It has strong chelating ability over a wide pH range, and its aqueous solution is acidic and easily hydrolyzed when heated (above 120 ℃). Application: Phytic acid, with its unique physiological, pharmacological and chemical properties, is widely used in metal surface treatment, metal corrosion prevention, electroplating, textile degreasing, solid reduction and yellowing of Baijiu, iron removal of wine, food and seafood preservation, etc. Standard: HG2683-95 Physical and chemical indicators: Content ≥ 50% Inorganic phosphorus ≤ 0.02% Calcium salt ≤ 0.02% Chloride ≤ 0.02% Sulfate ≤ 0.02% Arsenic ≤ 0.0003% Heavy metal ≤ 0.003%
