Chemical Structure

Ceftazidime EP Impurity C(2HCl) CAS 3432-88-0 (free base) chemical structure

Description

Compared with other compounds in its class, the molecular weight of 327.78 g/mol gives Ceftazidime EP Impurity C(2HCl) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Ceftazidime EP Impurity C(2HCl) (CAS 3432-88-0 (free base)) is a certified pharmaceutical impurity reference standard with the molecular formula C13H13N3O3SHCl and a molecular weight of 327.78 g/mol.

Ceftazidime EP Impurity C(2HCl) (C13H13N3O3SHCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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.

As a certified reference material (CRM), Ceftazidime EP Impurity C(2HCl) meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
