Chemical Properties

Formula Weight
404.46 (368.43anhy)
Melting point
ca 272° dec.
Soluble in water.


Ethylenediaminetetraacetic acid dipotassium salt dihydrate is used to eliminate inhibition of enzyme catalyzed reactions due to traces of heavy metals. It is involved in the study of chelators, biochemicals and reagents as well as in the study of the three dimensional hierarchy structures from self-assembly of quantum dots. It also acts as a catalyst by partially removing thiol stabilizers from the nanoparticle surface to induce the stabilization reaction of CdTe nanoparticles.


Incompatible with strong oxidizing agents and strong acids.
