Ferrous Fumarate: Key Chemical Properties and Applications
Introduction
Ferrous fumarate is an iron supplement widely used in pharmaceuticals and food fortification. Understanding its chemical properties is essential for proper handling and application.
Chemical Composition and Structure
Ferrous fumarate (C₄H₂FeO₄) consists of iron (Fe²⁺) bound to fumaric acid, a dicarboxylic acid. Its molecular weight is 169.9 g/mol, and it appears as a reddish-orange powder.
Solubility and Stability
– Solubility: Poorly soluble in water but dissolves in dilute acids.
– Stability: Stable under dry conditions but oxidizes in moist environments, converting ferrous iron (Fe²⁺) to ferric iron (Fe³⁺).
Reactivity
– Reacts with oxidizing agents, reducing its bioavailability.
– Decomposes at high temperatures (>280°C), releasing carbon dioxide and iron oxides.
Applications
– Pharmaceuticals: Treats iron-deficiency anemia due to high iron content (33% elemental iron).
– Food Fortification: Added to cereals and flour to prevent iron deficiency.
Safety Considerations
– Excessive intake may cause gastrointestinal irritation.
– Store in airtight containers to prevent oxidation.
Conclusion
Ferrous fumarate’s unique chemical properties make it a valuable iron supplement. Proper storage and handling ensure its effectiveness in medical and nutritional applications.
