Ferric Citrate

Updated: 2026-07-22

Overview

Ferric citrate, also known as iron(III) citrate, is an inorganic compound commonly used in various industrial and pharmaceutical applications. It is a chelating agent, which means it can bind to metal ions, making it useful in water treatment and as a dietary supplement for iron deficiency. This compound is typically available in the form of a brownish-yellow powder or granules. It is non-toxic and stable under normal conditions, but it should be handled with care to avoid unnecessary exposure.

Physical and Chemical Properties

Ferric citrate is characterized by its solubility in water and slight solubility in alcohol. It decomposes before melting, which is a key consideration during storage and handling. The compound acts as a chelating agent, making it effective in binding metal ions. Its molecular formula is C6H5FeO7, with a molecular weight of 244.95 g/mol. The brownish-yellow appearance is a distinguishing feature, and it is generally stable under standard conditions, though it should be protected from moisture and direct sunlight.

Main Applications

Ferric citrate is widely used in the pharmaceutical industry, particularly as an iron supplement for treating anemia. It is also employed in water treatment processes to remove phosphates and other contaminants. In the food industry, it serves as a dietary supplement and fortifier. Its chelating properties make it valuable in agricultural applications, where it is used to deliver iron to plants in a form they can easily absorb.

Safety and Storage

While ferric citrate is generally non-toxic, it should be handled with care to avoid inhalation or contact with eyes and skin. Protective equipment such as gloves and goggles is recommended during handling. Storage conditions are critical to maintaining the compound's stability. It should be kept in a cool, dry place, away from direct sunlight and moisture. Properly sealed containers are essential to prevent degradation.

B2B Procurement Guide

When procuring ferric citrate, B2B buyers should prioritize suppliers who provide certificates of analysis (COA) to ensure purity and quality. The reference price ranges from approximately $20 to $50 per kg, depending on purity and order quantity. Buyers should also consider the supplier's compliance with industry standards and regulations. Bulk purchases may offer cost savings, but storage capabilities should be assessed to maintain product integrity.
