Chemical Structure

Flomoxef Impurity 67 CAS CATO-C4X-138267 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 368.31 g/mol gives Flomoxef Impurity 67 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Flomoxef Impurity 67 (CAS CATO-C4X-138267) is a certified pharmaceutical impurity reference standard with the molecular formula C12H14F2N2O7S and a molecular weight of 368.31 g/mol.

Based on its molecular formula C12H14F2N2O7S, Flomoxef Impurity 67 contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 368.31 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

As a certified reference material (CRM), Flomoxef Impurity 67 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.
