Chemical Structure

Remdesivir Impurity 11 CAS 159326-68-8 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 134.14 g/mol gives Remdesivir Impurity 11 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Remdesivir Impurity 11 (CAS 159326-68-8), a pharmacopoeial impurity reference standard (molecular formula C6H6N4, MW 134.14 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Remdesivir Impurity 11 (C6H6N4) is characterized by a nitrile group, an aromatic ring system. 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 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).

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.

CATO manufactures Remdesivir Impurity 11 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.
