Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 777.09 g/mol gives Ioversol impurity 29 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Ioversol impurity 29 (CAS CATO-C4X-209129) is a certified pharmaceutical impurity reference standard with the molecular formula C17H22I3N3O8 and a molecular weight of 777.09 g/mol.
Structurally, Ioversol impurity 29 (C17H22I3N3O8) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, iodine substitution. 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 777.09 g/mol, it falls into the high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
As a certified reference material (CRM), Ioversol impurity 29 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.
