Product Name:Ethylenediaminetetraacetic Acid Dipotassium Salt
English Name:Ethylenediaminetetraacetic Acid Dipotassium Salt
CAS No.:25102-12-9
Aliases:EDTA dipotassium salt, Dipotassium ethylenediaminetetraacetate, Ethylenediaminetetraacetic acid dipotassium salt dihydrate
Molecular Formula:C10H14K2N2O8·2H2O
Physical Properties:White crystalline powder, freely soluble in water, slightly soluble in ethanol, insoluble in diethyl ether. The aqueous solution is weakly alkaline. It acts as a chelating agent that forms stable water-soluble complexes with various metal ions such as calcium and magnesium. Melting point approximately 245-250 °C (decomposition).
Uses:Mainly used as a metal ion chelating agent and complexometric titration reagent for the determination of metal ions such as calcium and magnesium. It is also commonly used as a masking agent for metal ions, and widely applied in the preparation of biological buffers, pharmaceutical analysis, and chemical production.
Technical Specifications:
Assay ≥99.0%
Appearance: white crystalline powder
Heavy metals (as Pb) ≤0.001%
Iron (Fe) ≤0.001%
Arsenic (As) ≤0.0005%
