Chemical Structure
Description
Structurally, Sodium 2-(carboxymethyl)-2-hydroxysuccinate (C6H6O7Na) contains a carbohydrate-derived structure. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 213.10 g/mol, it falls into the medium-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).
Sodium 2-(carboxymethyl)-2-hydroxysuccinate (CAS 144-33-2) is a high-purity analytical reference standard with the molecular formula C6H6O7Na and a molecular weight of 213.10 g/mol.
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.
