EDTA 2NA 139-33-3
SINOBIO
2922491990
Ethylenediaminetetraacetic Acid Disodium Salt (EDTA 2Na) is a white crystalline powder. It is odorless and tasteless, freely soluble in water and poorly soluble in ethanol. Its CAS number is 139-33-3. The following is a detailed introduction to EDTA 2Na:
Chemical Formula: C₁₀H₁₄N₂Na₂O₈ (anhydrous); C₁₀H₁₈N₂Na₂O₁₀·2H₂O (dihydrate)
Molecular Weight: 336.21 (anhydrous); 372.24 (dihydrate)
Appearance: White crystalline powder
Solubility: Freely soluble in water, poorly soluble in ethanol
pH of aqueous solution: Approximately 5.3
EDTA 2Na has important applications in the dye, food, and pharmaceutical industries. It prevents discoloration, deterioration, and turbidity caused by metals, as well as the oxidative loss of vitamin C. It also enhances the antioxidant properties of oils and fats. It is also used in solutions for electroless copper plating, gold plating, lead-tin alloy plating, electrochemical polishing of steel parts, and prior to silver plating of copper parts. It is also used in detergents, liquid soaps, shampoos, agricultural chemical sprays, bleaching and fixing solutions for processing color photographic materials, water purifiers, pH regulators, and anticoagulants.

EDTA 2Na is an important chelating agent that forms stable chelates with metal ions in solution, thereby preventing metal-induced discoloration, deterioration, turbidity, and oxidative loss of vitamin C.
In the food industry, EDTA 2Na is used as a preservative, antioxidant enhancer, and stabilizer. According to GB 2760-2014, EDTA 2Na can be used in foods such as jams, vegetable purees or sauces (excluding tomato sauce), preserved fruits (limited to sweet potato preserved fruits), pickled vegetables, canned vegetables, canned nuts and seeds, canned grains, and compound seasonings, but the maximum usage is limited.
EDTA 2Na also has important uses in the dye and pharmaceutical industries. It can be used in electroless copper plating, gold plating, lead-tin alloy plating, electrochemical polishing of steel parts, and in solutions before silver plating of copper parts. In addition, it can also be used in detergents, liquid soaps, shampoos, agricultural chemical sprays, color photographic material processing bleaching and fixing solutions, water purifiers, pH regulators and anticoagulants, etc.
* Preservatives and Preservatives: EDTA 2Na prevents discoloration, deterioration, and turbidity caused by metal ions in foods, as well as oxidative loss of vitamin C, thereby improving food shelf life and taste. It is commonly used in canned foods, processed meats, condiments, jams, vegetable purees or sauces, preserved fruits, pickled vegetables, canned vegetables, canned nuts and seeds, canned grains, compound seasonings, and beverages (excluding packaged drinking water).
* Nutrient Enhancer Carrier: In foods fortified with minerals such as calcium and iron, EDTA 2Na improves the solubility and bioavailability of these minerals.
* Water Treatment: EDTA 2Na effectively removes heavy metal ions from water, preventing water pollution. It also chelates metal ions, reducing water hardness, preventing boiler scaling, and extending the service life of equipment.
* Metalworking: EDTA 2Na can be used as an additive in metalworking to prevent metal surface oxidation, enhance metallic gloss, and extend the service life of metal products. *Dye Industry: EDTA 2Na stabilizes dyes, prevents dye decomposition, improves dyeing results, and enhances dye adhesion.
*Plastics and Rubber Industry: EDTA 2Na acts as a stabilizer for plastics and an antioxidant for rubber, preventing aging and extending their service life.
*Detergents and Cleansers: EDTA 2Na improves washing results and reduces detergent residue.
*Trace Element Supplementation: EDTA 2Na forms complexes with trace elements, increasing their absorption and utilization by plants and promoting plant growth.
*Soil Improvement: EDTA 2Na forms complexes with heavy metal ions in the soil, reducing their toxicity to plants and improving soil quality.
*Laboratory Reagents: EDTA 2Na is used to chelate metal ions and is widely used in chemical analysis.
*Photographic Chemicals: EDTA 2Na prevents discoloration in images.
*Textile Industry: EDTA 2Na prevents metal contamination and, as a dyeing auxiliary or finishing agent, improves the dyeing results and wearability of textiles. *Cosmetics and personal care products: EDTA 2Na acts as a stabilizer, preventing cosmetics from spoiling and extending their shelf life. It can also enhance the moisturizing properties of low-molecular-weight alcohol-based humectants (such as glycerin and polyethylene glycol 400).
Ethylenediaminetetraacetic acid disodium salt dehydrate is designated as Molecular Biology grade and is suitable for molecular biology applications. It has been analyzed for the presence of nucleases and protease.
