EDTA.CaNa2, EDTA Calcium Salt

CAS No.: 62-33-9

Molecular Formula:C₁₀H₁₂N₂O₈CaNa₂.2H₂O

Molecular Weight: 410.3

Structural Formula:

EDTA-CaNa2

Properties:

EDTA-CaNa₂ is applied as a trace element in agriculture and as a coloring agent and food additive in the food industry. It is difficult to be degraded. So, that means it is not an environment-friendly chemical. The COD (Chemical Oxygen Demand) Value is about 580 mg/g.

Frequency Asked Questions:

What is Calcium Disodium EDTA in Food?

EDTA-CaNa₂ generally does not cause significant harm to the human body, excessive intake or overuse may still have a certain risk and toxicity. Overuse of disodium EDTA may affect the kidneys and nervous system, and lead to symptoms such as kidney stones, kidney damage, and neurological abnormalities. In addition, calcium EDTA may bind with calcium ions, leading to the depletion of calcium ions and affecting the normal physiological functions of the body.

What is Calcium Disodium EDTA Used for?

In the industrial field, this EDTA calcium salt can be used in industries such as electroplating, textiles, printing and dyeing, pigments, paints, plastics, cosmetics, etc., as a complexing agent and stabilizer for metal ions to enhance product performance and stability. In the agricultural field, EDTA CaNa₂ can be used in pesticides and fertilizers to increase the stability of pesticides, improve fertilizer utilization, and promote crop growth. In the pharmaceutical field, CaNa₂ EDTA can be used to prepare complexes and chelates for drugs, thereby enhancing drug stability and efficacy. In the field of environmental protection, disodium calcium EDTA can be used for the chelation and adsorption of heavy metal ions, reducing the environmental pollution caused by heavy metal ions.
