EDTA-2Na The Optimal Chelating Agent for Preventing Metal-Induced Oxidation and Deterioration in Pharmaceutical Products

Ethylenediaminetetraacetic acid disodium salt, also known as EDTA-2Na, is a good complexing agent in chemistry. The chemical formula is C10H14N2Na2O8, with a molecular weight of 336.206. It has six coordinating atoms and forms a complex called a chelate. EDTA is often used in coordination titration to determine the content of metal ions. EDTA has important applications in industries such as dyes, food, and pharmaceuticals.
Ethylenediaminetetraacetic acid disodium is an odorless or slightly salty white or milky white crystalline or granular powder, odorless and tasteless. It can dissolve in water but is extremely difficult to dissolve in ethanol. It is an important chelating agent that can chelate metal ions in solution. Preventing discoloration, deterioration, turbidity caused by metals and oxidative loss of vitamin C can also enhance the antioxidant properties of oils (trace metals such as iron and copper in oils promote oil oxidation).

Among the salts of ethylenediaminetetraacetic acid, disodium salt is the most important. It is an important chelating agent. EDTA Na can also be used as a substitute for chemical copper plating, gold plating, lead tin alloy plating, electrochemical polishing of steel parts, and solutions before silver plating of copper parts. It is also used as detergent, liquid soap, shampoo, agricultural chemical spray, bleaching fixer, water purification agent, PH regulator, retarder, etc. In the chemical reduction initiation system for styrene butadiene rubber polymerization, disodium EDTA is used as an active agent to chelate ferrous ions and control the polymerization reaction rate.
