Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 526U7A2651 67-42-5 Egtazic acid Egtazic acid [USAN:INN] Acetic acid, (ethylenebis(oxyethylenenitrilo))tetra- 6,9-Dioxa-3,12-diazatetradecanedioic acid, 3,12-bis(carboxymethyl)- Ethylenebis(oxyethylenenitrilo)tetra(acetic acid) 4-04-00-02433 (Beilstein Handbook Reference) Acide egtazique [INN-French] Acido egtazico [INN-Spanish] Acidum egtazicum [INN-Latin] 1,2-Bis(2-dicarboxymethylaminoethoxy)ethane BRN 1717370 Ebonta EGTA EINECS 200-651-2 Ethylene glycol bis(aminoethyl ether)tetraacetate Ethylene glycol bis(beta-aminoethyl ether)-N,N'-tetraacetic acid Ethylene glycol bis(2-aminoethyl ether)tetraacetic acid Ethylene glycol bis(2-aminoethyl ether)-N,N,N',N'-tetraacetic acid Ethylene glycol, di(2-(N,N-dicarboxylmethyl)amino)ethyl ether (Ethylenebis(oxyethylenenitrilo))tetraacetic acid Ethylenedioxybis(ethyleneamino)tetraacetic acid Ethyleneglycol-bis(beta-aminoethyl ether)-N,N1-tetra-acetic acid Gedta Glycol-etherdiaminetetraacetic acid NSC 615010 Acide egtazique Acido egtazico Acidum egtazicum Ethylenebis(oxyethylenenitrilo)tetraacetic acid UNII-526U7A2651 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 380.35 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
