The disodium dihydrate form of EDTA, a hexadentate ligand used as a chelating agent. Due to its ability to sequester metal ions it has a wide range of uses, ranging from molecular biology to cosmetics and pharmaceutical research. In the biochemistry and molecular biology laboratory, EDTA disodium salt dihydrate can be used to deactivate enzymes when working with nucleic acids, proteins and polysaccharides. It is also used as a component in biological buffer solutions.

Disodium EDTA has the chemical formula of [CH2N(CH2CO2H)2]2, the molecular formula of C10H16N2O8, and is a major chelating agent from which all of its applications extend from. It has high affinity to free metal ions, a common pollutant and impurity in many chemical environments. As an example, when we clean something with soap or wash our laundry, there is a chemical reaction between the detergent, the organic dirt, and the water that provides an aqueous solution environment for the chemical reaction of "cleaning" to occur. However, many impurities and free metal ions and minerals in tap water makes the performance of detergents less effective and inconsistent across geographies with varying water quality. Disodium EDTA as a chelating agent helps bind the free radicals and impurities, allowing the major ingredients in detergents to work effectively and consistently without excessive "chemical disturbance."

Ethylenediaminetetraacetic acid disodium salt dihydrate is used as a chelator of divalent cations. It inhibits enzymes such as metalloproteases that require divalent cations for activity. It is also used in chelation therapy. It acts as a sequestering agent in shampoos, cleaners and other personal care products and serves as an anticoagulant for blood samples.
