Description

Ferric Citrate is an iron (III) salt of citric acid, recognized globally by the CAS registry number 2338-05-8. This compound serves as a critical source of bioavailable iron and functions as an effective phosphate binder, making it indispensable in sectors where precise metal ion chemistry and safety are paramount. It is a key material for manufacturers in the pharmaceutical, nutraceutical, food fortification, and water treatment industries seeking a reliable and high-purity iron source.

Application

• Pharmaceutical Active Ingredient: Primarily used as a phosphate binder in medications for patients with chronic kidney disease (CKD) to manage hyperphosphatemia.
• Nutraceutical & Food Fortification: Incorporated into dietary supplements and functional foods (e.g., flour, cereals) to address iron deficiency and anemia.
• Laboratory & Research Reagent: Employed in biochemical research and as a standard in analytical chemistry for iron quantification.
• Water Treatment: Acts as a coagulant and flocculant aid in the purification of drinking water and wastewater.
• Animal Feed Additive: Used in premixes to ensure adequate iron intake for livestock and poultry health.
• Industrial Catalyst & Intermediate: Serves as a catalyst precursor in certain organic synthesis reactions and as an intermediate in chemical manufacturing.

Quality Control

Our Ferric Citrate is manufactured under a strict quality management system. Production adheres to current Good Manufacturing Practices (cGMP) where applicable, and the product can be supplied to meet various pharmacopeial standards such as USP-NF or EP upon request. Every batch undergoes rigorous analytical testing, including assay, identification, and impurity profiling. A comprehensive Certificate of Analysis (COA) documenting purity, heavy metals, residual solvents, and microbiological data is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be kept away from excessive humidity. For long-term storage, consider using desiccants. Keep container tightly sealed when not in use to minimize oxidation and moisture absorption.
