English description（英文原文，共 1135 字符）
Product Name:Calcium Disodium EDTA
English Name:Calcium Disodium EDTA
CAS No.:39208-14-5
Aliases:Edetate calcium disodium, Calcium disodium edetate, Calcium disodium ethylenediaminetetraacetate, EDTA calcium disodium
Molecular Formula:C10H12CaN2Na2O8·xH2O
Physical Properties:White crystalline granules or white to grayish-white powder, slight salty taste, slightly hygroscopic, stable in air. Freely soluble in water, practically insoluble in ethanol. It chelates various metal ions to form stable water-soluble complexes, and its aqueous solution is weakly alkaline.
Uses:It is an excellent chelating agent that forms stable water-soluble complexes with various metal ions. In medicine, it is used as an antidote for heavy metal poisoning. In the food industry, it serves as an antioxidant, preservative and stabilizer to prevent oxidative deterioration caused by metal ions. It is also used in cosmetics, detergents and water treatment.
Technical Specifications:
Assay (dry basis) ≥ 99.0%
pH of 1% aqueous solution: 6.5–8.0
Heavy metals (as Pb) ≤ 0.002%
Arsenic (as As) ≤ 0.0003%
Clarity of aqueous solution: passes test
