Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 807.11 g/mol gives Ioversol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Ioversol (CAS 87771-40-2), molecular formula C18H24I3N3O9 and molecular weight 807.11 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Ioversol (C18H24I3N3O9) 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 807.11 g/mol, it falls into the 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.
CATO manufactures Ioversol under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
