Iohexol Impurity 48 CAS 2992672-98-5

Description

The occurrence of Iohexol Impurity 48 is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Iohexol Impurity 48 (CAS 2992672-98-5) is a certified pharmaceutical impurity reference standard with the molecular formula C18H22I3N3O8 and a molecular weight of 789.10 g/mol.

Structurally, Iohexol Impurity 48 (C18H22I3N3O8) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, iodine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 789.10 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).

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

As a certified reference material (CRM), Iohexol Impurity 48 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.
