Description
CATO supplies Flomoxef Impurity 10 (CAS CATO-C4X-138210), a pharmacopoeial impurity reference standard (molecular formula C5H8F2N2O2S, MW 198.19 g/mol) used for the identification and quantification of trace impurities in APIs.
Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, Flomoxef Impurity 10 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 198.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), Flomoxef Impurity 10 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.
