Ammonium Ferric Citrate: Formulas and Reliable Sourcing Guide

Introduction
Ammonium ferric citrate (AFC) is a versatile chemical compound used in various industries, including pharmaceuticals, food additives, and photography. Understanding its chemical formulas and sourcing reliable suppliers is crucial for quality assurance.

Chemical Formulas of Ammonium Ferric Citrate
Ammonium ferric citrate exists in two primary forms:

1. Brown Ammonium Ferric Citrate (C6H8O7·xFe·yNH3) – Contains higher iron content and is commonly used in medical applications.
2. Green Ammonium Ferric Citrate (C6H8O7·xFe·yNH3) – Has a lower iron concentration and is often used in food fortification.

Both forms are water-soluble and provide bioavailable iron, making them essential in nutritional supplements and industrial processes.

Key Applications
– Pharmaceuticals: Used in iron supplements to treat anemia.
– Food Industry: Acts as a food additive (E381) for iron fortification.
– Photography: Serves as a sensitizer in blueprints and cyanotype printing.

Reliable Sourcing of Ammonium Ferric Citrate
When sourcing AFC, consider the following:

1. Supplier Reputation: Choose manufacturers with ISO or GMP certifications to ensure high purity.
2. Purity Grades: Verify whether the product meets USP, BP, or food-grade standards.
3. Batch Testing: Ensure suppliers provide COA (Certificate of Analysis) for quality control.
4. Global Suppliers: Reliable sources include chemical distributors like Sigma-Aldrich, Alfa Aesar, and regional pharmaceutical-grade suppliers.

Conclusion
Ammonium ferric citrate is a critical compound with diverse applications. By understanding its formulas and sourcing from certified suppliers, businesses can ensure product quality and regulatory compliance.
