Chemical Structure

Avanafil Impurity 34 CAS 759408-08-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 113.16 g/mol gives Avanafil Impurity 34 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Avanafil Impurity 34 (CAS 759408-08-7) is a certified pharmaceutical impurity reference standard with the molecular formula C5H11N3 and a molecular weight of 113.16 g/mol.

The molecular framework of Avanafil Impurity 34 (C5H11N3) is characterized by a nitrile group. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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), Avanafil Impurity 34 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.
