Chemical Structure
Description
Ethylenediaminetetraacetic Acid Magnesium Disodium Salt (C10H12N2O8MgNa) contains a carbohydrate-derived structure, an amide group. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
Ethylenediaminetetraacetic Acid Magnesium Disodium Salt (CAS 14402-88-1) is a high-purity analytical reference standard with the molecular formula C10H12N2O8MgNa and a molecular weight of 335.51 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.
As a certified reference material (CRM), Ethylenediaminetetraacetic Acid Magnesium Disodium Salt meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
