Ammonium ferric citrate Structure

Synonyms: Ferric ammonium citrate, Ammonium iron(III) citrate, Iron ammonium citrate, FAC, CAS 1185-57-5

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.

Основные особенности продукта

  • High bioavailability: The chelated iron is readily absorbed, minimizing gastrointestinal irritation.
  • Excellent solubility: Freely soluble in water, ideal for liquid dosage forms.
  • Dual compliance: Available in USP, EP, and FCC grades to meet diverse regulatory needs.
  • Stable supply: Manufactured in our ISO 9001-certified facility with an annual capacity of 500 metric tons.
  • Quality assurance: Each batch is tested for iron content, heavy metals, and microbial limits.
  • Customizable packaging: Offered in 25 kg drums or small-scale aliquots for R&D.

Приложения
