Product Description
DDisodium ethylenediaminetetraacetate, often renowned in the chemical realm as EDTA-2Na, stands out for its exceptional ability to act as a complexing agent. With its chemical formula C10H14N2Na2O8 and a molecular weight of 336.206, this compound offers six coordinated atoms that form a stable structure known as a chelate. Esteemed for its pivotal role in complexometric titration, EDTA is extensively employed to precisely quantify metal ion concentrations. Its significance spans multiple industries, including dyes, food, and pharmaceuticals, where it has become indispensable.
Disodium EDTA presents itself as a versatile substance, available in a tasteless, odorless, or slightly saline white or milky white crystalline or granular powder form. While it dissolves readily in water, its solubility in ethanol is notably low. This vital chelating agent excels at binding metal ions in solutions, effectively preventing undesirable effects such as discoloration, deterioration, turbidity, and oxidative loss of valuable nutrients like vitamin C. Moreover, it enhances the antioxidant properties of oils and fats by mitigating the oxidative influence of trace metals, including iron and copper.
Among the EDTA salts, the disodium variant reigns supreme due to its unparalleled importance as a complexing agent. It finds extensive application in diverse fields such as chemical copper plating, gold plating, lead-tin alloy plating, and the electrochemical polishing of steel components. Additionally, it's utilized in preparatory solutions before silver-plating copper parts. Beyond this, disodium EDTA is integral to industries including detergents, liquid soaps, shampoos, agricultural chemicals, and photographic processing. It serves as a water purifier, pH regulator, and anticoagulant. Furthermore, in the realm of styrene-butadiene rubber polymerization, disodium EDTA plays a crucial role in the chemical reduction initiation system by complexing ferrous ions and controlling reaction rates.
