Chemical Structure
Description
Iron(III) sodium 2,2'-((2-((carboxylatomethyl)(2-((carboxylatomethyl)(carboxymethyl)amino)ethyl)amino)ethyl)azanediyl)diacetate (CAS 12389-75-2) is a high-purity analytical reference standard with the molecular formula C14H19N3O10FeNa and a molecular weight of 468.15 g/mol.
Structurally, Iron(III) sodium 2,2'-((2-((carboxylatomethyl)(2-((carboxylatomethyl)(carboxymethyl)amino)ethyl)amino)ethyl)azanediyl)diacetate (C14H19N3O10FeNa) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 468.15 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
