Selexipag Impurity 32 CAS 31600-69-8 chemical structure

Description

As a certified reference material (CRM), Selexipag Impurity 32 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.

Selexipag Impurity 32 (CAS 31600-69-8) is a certified pharmaceutical impurity reference standard with the molecular formula C7H16O2 and a molecular weight of 132.20 g/mol.

The molecular framework of Selexipag Impurity 32 (C7H16O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

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.
