Edaravone Impurity 15 CAS 27349-35-5

Description

Compared with other compounds in its class, the molecular weight of 188.23 g/mol gives Edaravone Impurity 15 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Edaravone Impurity 15 (CAS 27349-35-5), a pharmacopoeial impurity reference standard (molecular formula C11H12N2O, MW 188.23 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Edaravone Impurity 15 (C11H12N2O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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), Edaravone Impurity 15 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.
