Description

Ferric Ammonium Citrate is an iron coordination complex formed from ferric hydroxide and citric acid, neutralized with ammonia. This compound is valued for its bioavailability and stability, making it a preferred source of iron in critical formulations. It is essential for manufacturers in the pharmaceutical, food fortification, and analytical reagent industries seeking a consistent and high-purity iron source.

Application

• Pharmaceutical Ingredient: Used as an iron supplement in tablet and liquid formulations for treating iron-deficiency anemia.
• Food & Beverage Fortification: Serves as a nutritional additive (INS 381) to enrich foods like flour, cereals, and infant formula with bioavailable iron.
• Microbiological Culture Media: Acts as a source of soluble iron in the preparation of diagnostic and growth media in laboratories.
• Analytical Chemistry: Employed as a reagent in various colorimetric tests and as a standard in titrations.
• Blueprint Photography: Functions as a light-sensitive component in traditional cyanotype and blueprint processes.
• Animal Feed Premix: Incorporated into mineral premixes to prevent iron deficiency in livestock and poultry.

Quality Control

Our Ferric Ammonium Citrate is manufactured under strict quality management systems. It can be produced to meet various pharmacopeial standards such as USP-NF, Ph. Eur., and BP, as well as food-grade specifications (FCC). Every batch undergoes rigorous testing for identity, assay, and impurity profiles. A Certificate of Analysis (COA) documenting these results is provided with each shipment to ensure full traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and light-sensitive; prolonged exposure to air or light should be avoided to maintain stability and prevent caking.
