Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 412.44 g/mol gives Enarodustat Impurity 2 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Enarodustat Impurity 2 (CAS CATO-C4X-32282) is a certified pharmaceutical impurity reference standard with the molecular formula C21H24N4O5 and a molecular weight of 412.44 g/mol.
The molecular framework of Enarodustat Impurity 2 (C21H24N4O5) is characterized by a flavonoid core, an amide 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
As a certified reference material (CRM), Enarodustat Impurity 2 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.
