Ammonium ferric citrate industrial grade purity ≥ 99%, appearing as brownish red amorphous powder, odorless with faint iron‑like taste. It decomposes when heated at melting point; boiling point also decomposes. Vapor pressure is negligible at 25℃; relative density is 1.80 at 20℃. It is highly soluble in water but insoluble in ethanol, ether and chloroform. The product is stable and incompatible with strong acids, strong oxidizers and reducing agents.

Product Application
Ammonium ferric citrate serves as a food iron fortifier with better absorption than inorganic iron. In China, it is allowed in salt and sandwich sugar at 4000–8000 mg/kg; in iron‑fortified cereals and products (daily max 50 g): 1200–1350 mg/kg; dairy and infant foods: 400–800 mg/kg; cereals and products: 160–330 mg/kg; beverages: 70–140 mg/kg.
Fast delivery time
