EGTA is the chemical compound ethylene glycol tetraacetic acid, a chelating agent that is related to the better known EDTA, but with a much higher affinity for calcium than for magnesium ions. It is useful for making buffer solutions that resemble the environment inside living cells, where calcium ions are usually at least a thousandfold less concentrated than magnesium.
EGTA has also been used experimentally for the treatment of animals with cerium poisoning and for the separation of thorium from monazite.
