Product description

EDTA Tetrasodium, also known as ethylenediamine tetraacetic acid tetrasodium salt, is a chelating agent with the chemical formula C10H12N2O8Na4. Here's a brief description:
  1. Chemical Structure: EDTA Tetrasodium is a sodium salt of ethylenediamine tetraacetic acid (EDTA). It contains four carboxyl groups (-COOH) and two amine groups (-NH2) arranged around a central ethylenediamine backbone.
  2. Physical Properties:
    • Appearance: EDTA Tetrasodium is typically a white, crystalline powder.
    • Solubility: It is highly soluble in water.
  3. Synthesis: EDTA Tetrasodium is synthesized by the reaction of ethylenediamine with formaldehyde and sodium cyanide, followed by hydrolysis and neutralization.
  4. Applications:
    • Chelating Agent: EDTA Tetrasodium is primarily used as a chelating agent to bind metal ions, such as calcium, magnesium, iron, and copper, in various industrial, pharmaceutical, and household products. It helps prevent the adverse effects of metal ions, such as oxidation, precipitation, and enzyme inhibition.
    • Water Treatment: It is employed in water treatment processes to sequester metal ions and prevent scale formation in boilers and pipes.
    • Food and Beverage Industry: EDTA Tetrasodium is used as a food additive (E number E385) to improve the stability and shelf life of processed foods and beverages by chelating metal ions that catalyze oxidation reactions.
    • Medical Applications: It is utilized in medical and pharmaceutical formulations, such as in chelation therapy for heavy metal poisoning and as a stabilizing agent in certain medications.
    • Laboratory Use: EDTA Tetrasodium is used in laboratories for various analytical and research purposes, such as in titrations and complexometric analysis.
  5. Health and Safety Considerations:
    • EDTA Tetrasodium is generally regarded as safe when used in accordance with good manufacturing practices and applicable regulations.
    • It is non-toxic, non-corrosive, and non-flammable.
    • However, ingestion of large quantities may cause gastrointestinal irritation.
  6. Environmental Impact:
    • EDTA Tetrasodium may have environmental implications if released into water bodies. However, its impact is generally mitigated through proper handling, wastewater treatment, and biodegradation.
