Chemical Structure

Edaravone Impurity N2 CAS 168848-20-2 chemical structure

Description

CATO supplies Edaravone Impurity N2 (CAS 168848-20-2), a pharmacopoeial impurity reference standard (molecular formula C20H18N4O, MW 330.38 g/mol) used for the identification and quantification of trace impurities in APIs.

Edaravone Impurity N2 (C20H18N4O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 Edaravone Impurity N2 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.
