Ethylenebis(oxyethylenenitrilo)tetraacetic acid Chemical Properties,Uses,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.

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ChEBI: A diether that is ethylene glycol in which the hydrogens of the hydroxy groups have been replaced by 2-[bis(carboxymethyl)amino]ethyl group respectively.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

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.]
