Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 233.22 g/mol gives Cefprozil EP Impurity C(Cefadroxil EP Impurity E) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
As a process- or degradation-related impurity, Cefprozil EP Impurity C(Cefadroxil EP Impurity E) (CAS 147103-93-3, C11H11N3O3) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, Cefprozil EP Impurity C(Cefadroxil EP Impurity E) is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 233.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 Cefprozil EP Impurity C(Cefadroxil EP Impurity E) 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.
