Chemical Structure

Avanafil Impurity N59 CAS 27427-92-5 chemical structure

Description

As a certified reference material (CRM), Avanafil Impurity N59 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.

CATO supplies Avanafil Impurity N59 (CAS 27427-92-5), a pharmacopoeial impurity reference standard (molecular formula C5H4N2O, MW 108.10 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Avanafil Impurity N59 (C5H4N2O) is characterized by 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 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.
