Chemical Structure
Description
CATO supplies Faropenem Impurity 26 (CAS CATO-C4X-128926), a pharmacopoeial impurity reference standard (molecular formula C12H14NO6SNa, MW 323.30 g/mol) used for the identification and quantification of trace impurities in APIs.
Faropenem Impurity 26 (C12H14NO6SNa) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
