Ferric Sodium EDTA (CAS 15708-41-5) is a stable chelated iron complex supplied as a yellow-brown, highly water-soluble powder that keeps iron bioavailable in food fortification, agricultural micronutrient and industrial water treatment systems. This Agriculture Grade micronutrient is essential for correcting iron deficiency in crops grown in alkaline or calcareous soils.
In the Food Grade sector, it is the preferred iron fortificant for flour and condiments because it does not promote oxidation or metallic flavors. Its chemically stable chelate ring prevents the iron from reacting with other food components like phytates.
The yellow-brown powder is highly water-soluble and provides a consistent iron source for both foliar and soil applications. It is recognized globally for its effectiveness in combating iron-deficiency anemia through large-scale food enrichment programs.

Ferric Sodium EDTA
Applications
- Agricultural Micronutrient: Prevents leaf yellowing (chlorosis) in high-value crops, ensuring optimal photosynthesis and crop yields.
- Food Fortification: Used to enrich wheat flour, corn meal, and powdered beverages with iron without affecting sensory quality.
- Industrial Water Treatment: Acts as a sequestering agent to control transition metal ions and prevent catalytic oxidation in aqueous systems.
