Chemical Structure

Ornidazole Impurity 55 CAS CATO-C4X-133155 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 238.07 g/mol gives Ornidazole Impurity 55 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

As a process- or degradation-related impurity, Ornidazole Impurity 55 (CAS CATO-C4X-133155, C7H9Cl2N3O2) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Ornidazole Impurity 55 (C7H9Cl2N3O2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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.

CATO manufactures Ornidazole Impurity 55 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.
