Description
CATO manufactures Ornidazole Impurity 51 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.
As a process- or degradation-related impurity, Ornidazole Impurity 51 (CAS CATO-C4X-133151, C15H21Cl2N5O11P2) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Owing to a flavonoid core, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage, chlorine substitution, Ornidazole Impurity 51 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 580.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
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.
