Description
Cefminox impurity 51 (CAS CATO-C4X-192651) is a certified pharmaceutical impurity reference standard with the molecular formula C15H20N2O8S2 and a molecular weight of 420.46 g/mol.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Cefminox impurity 51 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 420.46 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
CATO manufactures Cefminox impurity 51 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
