Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 654.80 g/mol gives Cefcapene Impurity 8 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Cefcapene Impurity 8 (CAS 153012-37-4), a pharmacopoeial impurity reference standard (molecular formula C22H27N5O8S2C6H15N, MW 654.80 g/mol) used for the identification and quantification of trace impurities in APIs.
Cefcapene Impurity 8 (C22H27N5O8S2C6H15N) 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 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 Cefcapene Impurity 8 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.
