Pirfenidone Impurity 41 CAS 1824-81-3 chemical structure

Description

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.

Pirfenidone Impurity 41 (CAS 1824-81-3) is a certified pharmaceutical impurity reference standard with the molecular formula C6H8N2 and a molecular weight of 108.14 g/mol.

Based on its molecular formula C6H8N2, Pirfenidone Impurity 41 contains a nitrile group, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 108.14 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

As a certified reference material (CRM), Pirfenidone Impurity 41 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.
