Description
As a certified reference material (CRM), Meglumine Diatrizoate 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.
Meglumine Diatrizoate (CAS 131-49-7) is a high-purity analytical reference standard with the molecular formula C11H9I3N2O4C7H17NO5 and a molecular weight of 809.12 g/mol.
Based on its molecular formula C11H9I3N2O4C7H17NO5, Meglumine Diatrizoate contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, iodine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 809.12 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
