Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 377.33 g/mol gives Marbofloxacin Impurity 10 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Marbofloxacin Impurity 10 (CAS CATO-C4X-180010), a pharmacopoeial impurity reference standard (molecular formula C16H16FN5O5, MW 377.33 g/mol) used for the identification and quantification of trace impurities in APIs.
Structurally, Marbofloxacin Impurity 10 (C16H16FN5O5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 377.33 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
