Chemical Structure

Iopromide Impurity 19 CAS CATO-C4X-183219 chemical structure

Description

The occurrence of Iopromide Impurity 19 is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Iopromide Impurity 19 (CAS CATO-C4X-183219) is a certified pharmaceutical impurity reference standard with the molecular formula C5H13N3O2 and a molecular weight of 147.18 g/mol.

Based on its molecular formula C5H13N3O2, Iopromide Impurity 19 contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 147.18 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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), Iopromide Impurity 19 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.
