High Quality 100.4% Ferrous sulfate heptahydrate CAS 7782-63-0 for Fine Chemical

Details:

Ferrous Sulfate Heptahydrate is a hydrated iron salt widely used as a dietary supplement and industrial chemical. Here's a detailed breakdown:

Chemical Composition & Properties

• Formula: FeSO?·7H?O

• Structure: Iron(II) sulfate combined with 7 water molecules (heptahydrate).

• Appearance: Blue-green crystalline solid.

• Solubility: Highly soluble in water; iron is in the +2 oxidation state (ferrous).

• Stability: Slowly oxidizes in moist air to form ferric sulfate (Fe³?); store in airtight containers.

Primary Uses

1. Medical:

   • Iron Supplement: Treats/prevents iron deficiency anemia (common in pregnancy, chronic bleeding, or poor dietary intake).

   • Available as tablets, capsules, or liquid formulations (e.g., brands like Feosol).

2. Agricultural:

   • Fertilizer: Corrects iron-deficient soils (e.g., chlorosis in plants).

   • Moss Control: Applied to lawns to inhibit moss growth by lowering soil pH.

3. Industrial:

   • Water Treatment: Coagulant for removing phosphates and impurities.

   • Dye & Pigment Production: Mordant in textile dyeing; precursor for iron oxide pigments.

   • Laboratory Reagent: Used in chemical synthesis and analytical chemistry.

Safety & Side Effects

• Common Side Effects (oral use):

  • Gastrointestinal issues (nausea, constipation, black stools).

  • Metallic taste, stomach cramps.

• Serious Risks:

  • Iron Toxicity: Overdose can cause vomiting, organ failure, and metabolic acidosis (fatal in children if >20 mg/kg).

  • Drug Interactions: Reduces absorption of tetracyclines, levothyroxine, and quinolones (space doses 2–4 hours apart).

• Contraindications: Hemochromatosis, thalassemia, or other iron overload disorders.

Handling & Storage

• Storage: Keep in airtight, moisture-proof containers to prevent oxidation.

• Handling: Wear gloves to avoid staining; avoid inhalation of dust.

• Disposal: Follow local regulations to prevent environmental contamination (excess iron harms aquatic ecosystems).

Key Considerations

• Bioavailability: Enhanced by vitamin C (ascorbic acid) when taken orally.

• Regulations:

  • Listed on the WHO Model List of Essential Medicines.

  • Regulated as a pharmaceutical product (dose limits, child-resistant packaging).

• Environmental Impact: Overuse in agriculture can acidify soils or contaminate waterways.

Alternatives

• Other iron supplements (e.g., ferrous gluconate, ferric citrate) for patients intolerant to sulfate.

• Chelated iron (e.g., EDTA-Fe) in agriculture for better soil stability.

Ferrous sulfate heptahydrate is indispensable in healthcare and industry, but requires careful use to balance efficacy with safety. Always consult a healthcare provider for medical applications.
