2,2',2'',2'''-(1,2-Ethanediyldinitrilo)tetraacetic acid(CAS: 60-00-4)

2,2',2'',2'''-(1,2-Ethanediyldinitrilo)tetraacetic acid, also known as ethylenediaminetetraacetic acid (EDTA), is a chelating agent with the chemical formula C10H16N2O8. It is a white, crystalline solid that is highly soluble in water. EDTA is known for its ability to bind metal ions, making it useful in various chemical applications. Its structure includes four carboxylate groups and two amine groups, which contribute to its strong complexing properties.

EDTA is widely used in pharmaceuticals, industry, and food as a chelating agent. It helps in removing heavy metals from solutions, stabilizing products, and preventing oxidation. In research, it is used for metal ion sequestration in analytical chemistry. EDTA is also found in detergents and as a preservative in cosmetics. Its applications are supported by its high solubility and strong binding affinity with metal ions.

EDTA is generally considered safe when used properly. It is non-toxic in low concentrations and has low acute toxicity. However, prolonged exposure or ingestion can cause health issues. Proper handling, including using gloves and working in a well-ventilated area, is recommended. Safety standards ensure its use in regulated industries, and it is approved for food and pharmaceutical applications.

EDTA should be stored in a cool, dry place away from light. It is typically kept in airtight containers to prevent moisture absorption. The recommended storage temperature is between 15°C to 25°C, with humidity levels below 60%. Proper storage ensures its stability and effectiveness, as it can degrade if exposed to high temperatures or excessive moisture.
