Compared with other compounds in its class, the molecular weight of 552.71 g/mol gives Bifonazole EP Impurity E(Mixture of Diastereomers) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
As a process- or degradation-related impurity, Bifonazole EP Impurity E(Mixture of Diastereomers) (CAS 2469554-07-0, C41H32N2) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, Bifonazole EP Impurity E(Mixture of Diastereomers) is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 552.71 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.
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.
