delafloxacin Impurity 2 CAS CATO-C4X-26372

Description

Compared with other compounds in its class, the molecular weight of 808.43 g/mol gives delafloxacin Impurity 2 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

delafloxacin Impurity 2 (CAS CATO-C4X-26372) is a certified pharmaceutical impurity reference standard with the molecular formula C33H17Cl2F6N7O7 and a molecular weight of 808.43 g/mol.

Based on its molecular formula C33H17Cl2F6N7O7, delafloxacin Impurity 2 contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 808.43 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
