| | Ethylenebis(oxyethylenenitrilo)tetraacetic acid Usage And Synthesis |
| Description | Ethylenebis(oxyethylenenitrilo)tetraacetic acid is also named as Egtazic acid. It works as a chelating agent for the determination of calcium in the presence of magnesium.
| | Chemical Properties | White to slightly off-white powder | | Uses | A chelating agent useful for the determination of calcium in the presence of magnesium. | | Uses | Ethylene glycol-O,O'-bis(2-aminoethyl)-N,N,N',N'-tetraacetic acid is a chelating agent used for making complexes, especially for calcium ions, which help to determine calcium in the presence of magnesium. It can be used experimentally for treating animals possessing cerium poisoning. It is useful in the separation of thorium from monazite. It also acts as a buffer and is used in protein purification. | | Uses | Pharmaceutic aid. EGTA. | | Definition | ChEBI: A diether that is ethylene glycol in which the hydrogens of the hydroxy groups have been replaced by 2-[bis(carboxymethyl)amino]ethyl group respectively. | | Biological Activity | Calcium chelator; protects against cell death caused by nitric oxide-induced calcium influx into nerve cells. | | Safety Profile | Poison by
intraperitoneal route. Moderately toxic by
ingestion. When heated to decomposition it
emits toxic fumes of NOx. See also
