Product Name:3,6-Dioxa-1,8-octanediamine-N,N,N',N'-tetraacetic acid tetrasodium salt
English Name:3,6-Dioxa-1,8-octanediamine-N,N,N',N'-tetraacetic acid tetrasodium salt
CAS No.:13368-13-3
Aliases:EGTA tetrasodium salt, Ethylene glycol-bis(2-aminoethyl ether)-N,N,N',N'-tetraacetic acid tetrasodium salt, EGTA-4Na
Molecular Formula:C14H20N2Na4O10
Physical Properties:White crystalline powder, freely soluble in water, slightly soluble in ethanol and other organic solvents, insoluble in nonpolar organic solvents. The pH of a 1% aqueous solution is about 10-11. It decomposes above 300°C. It has strong metal-chelating ability, forming stable complexes with calcium, magnesium and other metal ions.
Uses:As a chelating agent, it is widely used in analytical chemistry for complexometric titration and photometric determination of metal ions such as calcium and magnesium. In biological and biochemical research, it is used to prepare buffer solutions and remove trace heavy metal ions from systems. It is also applied in detergents and separation processes for chelating metal ions.
Technical Specifications:
Purity (dry basis) ≥ 98%
Appearance: white crystalline powder
Solubility: soluble in water, 10% aqueous solution is clear and transparent
pH of 1% aqueous solution: 10-11
Melting point: >300°C (decomposition)
