Ammonium ferric citrate is a water-soluble iron(III) complex formed by the reaction of ferric citrate with ammonium citrate. It appears as reddish-brown crystals or granules, is freely soluble in water, and is available in both pharmaceutical and food-grade qualities. The compound is prized for its high bioavailability and excellent stability in aqueous solutions, making it a preferred iron source in liquid formulations.
In the pharmaceutical and nutraceutical industries, it is widely used as an iron supplement for treating iron-deficiency anemia, often incorporated into syrups and drops. As a food additive (INS 381), it serves as an acidity regulator and iron fortifier. Additionally, it finds applications in photography, water treatment, and as a catalyst in organic synthesis. Its compatibility with a wide range of excipients and its neutral taste profile make it particularly suitable for pediatric and geriatric formulations.
