Description

Structurally, 85233-19-8 K22DDW77C0 1,2-Bis(2-aminophenoxy)ethane-N,N,N',N'-tetraacetic acid Glycine, N,N'-(1,2-ethanediylbis(oxy-2,1-phenylene)bis(N-(carboxymethyl)- Glycine, N,N'-(1,2-ethanediylbis(oxy-2,1-phenylene))bis(N-(carboxymethyl)-,tetrapotassium salt Bapeta BAPTA 1,2-Bis(o-aminophenoxy)ethane-N,N,N',N'-tetraacetic acid Ca(II)-bapta UNII-K22DDW77C0 (C22H36N2O10) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 488.53 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
