Chemical Structure

Cloxacillin Impurity N2 CAS 69399-79-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 274.08 g/mol gives Cloxacillin Impurity N2 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

As a process- or degradation-related impurity, Cloxacillin Impurity N2 (CAS 69399-79-7, C11H6Cl2FNO2) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Cloxacillin Impurity N2 (C11H6Cl2FNO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

As a certified reference material (CRM), Cloxacillin Impurity N2 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
