Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 464.53 g/mol gives Cefdinir Impurity 85 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
As a process- or degradation-related impurity, Cefdinir Impurity 85 (CAS CATO-C4X-121085, C25H24N2O5S) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Cefdinir Impurity 85 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 464.53 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
CATO manufactures Cefdinir Impurity 85 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.
