Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 487.43 g/mol gives Capecitabine Impurity 40 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Capecitabine Impurity 40 (CAS CATO-C4X-102440), a pharmacopoeial impurity reference standard (molecular formula C20H26FN3O10, MW 487.43 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C20H26FN3O10, Capecitabine Impurity 40 contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 487.43 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), Capecitabine Impurity 40 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.
