Description
CATO manufactures Cefdinir Impurity C84 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.
Cefdinir Impurity C84 (CAS 178422-45-2) is a certified pharmaceutical impurity reference standard with the molecular formula C14H15N5O6S2 and a molecular weight of 413.43 g/mol.
Based on its molecular formula C14H15N5O6S2, Cefdinir Impurity C84 contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 413.43 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.
