Chemical Structure
Description
As a process- or degradation-related impurity, Ornidazole Impurity 78 (CAS CATO-C4X-133178, C7H11N3Na2O10P2) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Owing to a carbohydrate-derived structure, an amide group, a phosphate ester group, Ornidazole Impurity 78 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 405.10 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
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.
