Ethylenebis(oxyethylenenitrilo)tetraacetic acid Chemical Properties,Usage,Production

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ChEBI: A diether that is ethylene glycol in which the hydrogens of the hydroxy groups have been replaced by 2-[bis(carboxymethyl)amino]ethyl group respectively.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.

storage

Room temperature

Purification Methods

Dissolve EGTA in aqueous NaOH, precipitate it by adding aqueous HCl, wash it with water and dry at 100o in vacuo.[Beilstein 4 IV 217.]
