EDTA-4NA

EDTA, or ethylenediaminetetraacetic acid, is synthesized by reacting ethylenediamine with chloroacetic acid in the presence of sodium hydroxide. The reaction yields it along with sodium chloride. Physical properties of it include a white crystalline powder appearance, with a melting point of around 240-250°C. It is sparingly soluble in cold water but readily dissolves in hot water and acids. It is a chelating agent, forming stable complexes with metal ions, and is widely used in industries such as pharmaceuticals, detergents, and water treatment for its ability to sequester metal ions.

EDTA, or ethylenediaminetetraacetic acid, is a versatile chelating agent commonly used in various industrial, medical, and scientific applications due to its ability to bind metal ions. One of its special applications is in medicine, where EDTA is used as a chelating agent to treat heavy metal poisoning. EDTA forms stable complexes with toxic metals such as lead, mercury, cadmium, and arsenic, facilitating their excretion from the body. This chelation therapy is particularly important in cases of acute or chronic heavy metal poisoning, helping to reduce toxicity and mitigate associated health risks. Additionally, EDTA 4NA (tetrasodium salt of EDTA) is utilized in various laboratory procedures, including molecular biology and biochemistry, where precise metal ion concentrations are crucial for experimental accuracy.
