EGTA Buffer CAS 67-42-5 Biological Buffers Biochemistry
Ethylene glycol tetraacetic acid (EGTA) is a common buffer ingredient due to its chelating activity. It is similar to the better known EDTA, but has a much higher affinity for calcium ions than for magnesium ions. Buffers made with EGTA are used in some cases to mimic the environment inside living cells where calcium ions are usually at least a thousandfold less concentrated than magnesium ions.

| 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 | Pharmaceutic aid. EGTA. |
| 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 | A chelating agent useful for the determination of calcium in the presence of magnesium. |
| Definition | ChEBI: A diether that is ethylene glycol in which the hydrogens of the hydroxy groups have been replaced by 2-[bis(carboxymethyl)amino]ethyl group respectively.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 GLYCOL ETHERS. |
