Chemical Structure

Flomoxef Impurity 13 CAS CATO-C4X-138213 chemical structure

Description

As a certified reference material (CRM), Flomoxef Impurity 13 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.

As a process- or degradation-related impurity, Flomoxef Impurity 13 (CAS CATO-C4X-138213, C6H8F2N2OS) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Flomoxef Impurity 13 (C6H8F2N2OS) contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point; 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.
