일반 설명

Ethylenediaminetetraacetic acid disodium salt dihydrate (EDTA-Na₂), is a well known complexation agent with various uses in chemical synthesis, analytical chemistry, and biochemistry. In chemical synthesis, EDTA-Na₂ combines with polyvalent cations to form a soluble non-ionic complex that can be removed from solution, which helps prevent undesired side reactions.
