688-57-3 Usage

Definition

ChEBI: An ethylenediamine derivative in which three of the four amine protons of ethylenediamine are replaced by carboxymethyl groups.

Check Digit Verification of cas no

The CAS Registry Mumber 688-57-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,8 and 8 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 688-57:
(5*6)+(4*8)+(3*8)+(2*5)+(1*7)=103
103 % 10 = 3
So 688-57-3 is a valid CAS Registry Number.

Facile and Selective Conversion of Ethylenediaminetetraacetate to Ethylenediamine-N,N,N'-triacetate on a Cobalt Complex

Yashiro, Morio,Mori, Tomonori,Yoshikawa, Sadao,Shiraishi, Shinsaku

, p. 1009 - 1012 (1993)

Ethylenediaminetetraacetatocobaltate(III) is converted to aqua(ethylenediamine-N,N,N'-triacetato)cobalt(III) selectively in a 1 mol dm-3 K2CO3 aqueous solution at room temperature in the presence of PbO2.This reaction could be a simple and versatile procedure to obtain ed3a-type ligands.

The iron(III)-catalyzed oxidation of EDTA in aqueous solution

Motekaitis, Ramunas J.,Martell, Arthur E.,Hayes, David,Frenier, Wayne W.

, p. 1999 - 2005 (2007/10/02)

At temperatures above 100 deg C iron(III) oxidizes coordinated EDTA to ethylenediaminetriacetic acid in aqueous solution in the absence of molecular oxygen.The reaction proceeds with an activation energy of 28.6 kcal/mol, and its rate is directly proportional to the concentration of Fe(III) and inversely proportional to pH.At 125 deg C, the halflife of Fe(III) in the presence of excess EDTA is about 3 h at pH 9.3, but increases to >70 h at pH 5.4.The reaction is stoichiometric and no other reaction products or by-products were detected by nmr, gc, and gc - mass spectroscopy.In the presence of oxygen iron catalyzes quantitative oxidation of ethylenediamine-N,N,N',N'-tetraacetic acid (EDTA) to ethylenediaminetriacetic acid.The copper(II)-EDTA chelate undergoes a similar reaction but higher temperatures (>/=170 deg C) are required.Iron(III) also oxidizes nitrilotriacetic acid (NTA) to iminodiacetic acid (IDA) and glycine.The hydrolyzed species Fe(OH)EDTA is shown to be the reactive intermediate, and the well-known (Fe-EDTA)2O(4-) μ-oxo dimer is shown not to exist at elevated temperatures (above 100 deg C).Probable mechanisms are proposed for these reactions and comparisons are made with earlier work.
