Ethylenediaminetetraacetic acid dipotassium salt dehydrate can be used to study chelators, biochemicals and reagents. Ethylenediaminetetraacetic acid dipotassium salt dehydrate has been used to study the three dimensional hierarchy structures from self-assembly of quantum dots. Ethylenediaminetetraacetic acid dipotassium salt dehydrate acts as a catalyst by partially removing thiol stabilizers from the nanoparticle surface to induce the stabilization reaction of CdTe nanoparticles.
