Cefdinir CP Impurity C CAS 79349-82-9

Description

Compared with other compounds in its class, the molecular weight of 226.25 g/mol gives Cefdinir CP Impurity C distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Cefdinir CP Impurity C (CAS 79349-82-9) is a certified pharmaceutical impurity reference standard with the molecular formula C9H10N2O3S and a molecular weight of 226.25 g/mol.

The molecular framework of Cefdinir CP Impurity C (C9H10N2O3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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 CP Impurity C 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.
