Chemical Structure

Iomeprol Impurity 13 CAS CATO-C4X-182013 chemical structure

Description

The molecular framework of Iomeprol Impurity 13 (C16H22O5) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Iomeprol Impurity 13 (CAS CATO-C4X-182013) is a certified pharmaceutical impurity reference standard with the molecular formula C16H22O5 and a molecular weight of 294.34 g/mol.

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.

CATO manufactures Iomeprol Impurity 13 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.
