What is Ferric Sodium EDTA CAS 15708-41-5?
Chemical name: Sodium ethylenediamine tetraacetic Acid iron (Ethylenediaminetetraacetic Acid Ferric Sodium Salt)
Molecular formula: C ₁ zero H ₁ ₂ FeN ₂ NaO ₈ (no water) or C ₁ zero H ₁ ₂ FeN ₂ NaO ₈ · 3 H ₂ O (including crystallization water)
Molecular weight: 367.05 g/mol (anhydrous) | 421.10 g/mol (trihydrate)
CAS Number: 15708-41-5
Iron content: 12.5-13.5%
Appearance: Light yellow to yellowish-brown crystalline powder, readily soluble in water, no rust-like taste
Food-grade preferred
Select products with iron content ≥12.8% and water-insoluble matter ≤0.1% (GB 22557-2008).
Industrial-grade substitution
Low-cost ferrous sulfate can be used in water treatment scenarios, but the complexation efficiency is 30% lower.
Emerging opportunities
Functional foods: Targeting the elderly/pregnant women market, the demand is increasing by 8% annually.
Embedding technology: Combined with VC or phospholipids to enhance bioavailability.
Ferric Sodium EDTA CAS 15708-41-5 Use
Food nutrient fortifiers (accounting for 45% of the demand)
Function: Highly efficient iron supplement, with an absorption rate 2 to 3 times that of ferrous sulfate, avoiding the obstruction of phytic acid.
Applicable products: Infant and toddler food, milk beverages, fruit juice (addition amount: 0.1-1%), can improve anemia without changing the color and flavor of food.
industrial field
Water treatment: Complexing heavy metal ions (such as lead and cadmium), accounting for 40% of global demand.
Photosensitive material: Used as a bleaching agent and thinning agent (for developing black-and-white films).
Printing and dyeing and catalysis: Enhancing the stability of dyes and the efficiency of chemical reactions.
Agriculture and Medicine
Foliar fertilizer: Provides absorbable iron elements and enhances the crop's stress resistance.
Pharmaceutical excipients: Chelating agents for pharmaceuticals, promoting the absorption of trace elements.
Ferric Sodium EDTA CAS 15708-41-5 safety
Health risk:
It is irritating to the skin and eyes (R36/37/38). A gas mask and acid and alkali resistant gloves should be worn during operation.
Chronic toxicity: Oral LD₅₀ in rats =2000 mg/kg. Protection is required for long-term exposure.
Storage requirements:
Keep sealed and away from light. Store in a dry place at ≤25℃ with a relative humidity of less than 75%.
Environmental protection compliance
Exports to the European Union require REACH certification, and food applications need to comply with GB 2760 and FDA standards.
