Chemical Structure

Ornidazole Impurity 74 CAS CATO-C4X-133174 chemical structure

Description

The occurrence of Ornidazole Impurity 74 is closely related to an amide group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

As a process- or degradation-related impurity, Ornidazole Impurity 74 (CAS CATO-C4X-133174, C7H10Cl2N3O5P) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Owing to an amide group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, Ornidazole Impurity 74 is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 318.05 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
