Description
CATO manufactures Cefalotin EP Impurity C/Cefoperazone EP Impurity E/Cefazolin EP Impurity H 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.
As a process- or degradation-related impurity, Cefalotin EP Impurity C/Cefoperazone EP Impurity E/Cefazolin EP Impurity H (CAS 957-68-6, C10H12N2O5S) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Cefalotin EP Impurity C/Cefoperazone EP Impurity E/Cefazolin EP Impurity H (C10H12N2O5S) 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.
