Chemical Structure
Description
Sodium 2,2'-((2-((carboxylatomethyl)(2-hydroxyethyl)amino)ethyl)azanediyl)diacetate hydrate (CAS 313222-79-6), molecular formula C10H15N2O7NaH2O and molecular weight 316.24 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Sodium 2,2'-((2-((carboxylatomethyl)(2-hydroxyethyl)amino)ethyl)azanediyl)diacetate hydrate (C10H15N2O7NaH2O) contains a carbohydrate-derived structure, an amide group. The molecule exhibits a degree of unsaturation (DBE) of 3.5, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 316.24 g/mol, it falls into the moderately-high-molecular-weight range. 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.
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.
