Chemical Structure

Mebendazole impurity 3 CAS CATO-C4X-27683 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 324.29 g/mol gives Mebendazole impurity 3 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

As a process- or degradation-related impurity, Mebendazole impurity 3 (CAS CATO-C4X-27683, C16H12N4O4) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Mebendazole impurity 3 (C16H12N4O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), Mebendazole impurity 3 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.
