Ethylenediaminetetraacetic acid disodium magnesium salt tetrahydrate, also known as EDTA.Mg.2Na.4H2O, is utilized to sequester divalent cations, including calcium, magnesium, and iron. It′s used to stabilize proteins, enzymes, and other biological molecules for laboratory experiments. It also assists in removing heavy metals from solutions and aids in the separation of proteins and nucleic acids. Ethylenediaminetetraacetic acid disodium magnesium salt tetrahydrate operates by binding to metal ions through chelation, forming a stable complex with these ions and preventing their interaction with other molecules. This compound′s high affinity for metal ions allows it to form a complex that is resilient to chemical and thermal degradation.
