Nitrendipine Impurity 12 CAS 22502-03-0 chemical structure

Description

Nitrendipine Impurity 12 (CAS 22502-03-0) is a certified pharmaceutical impurity reference standard with the molecular formula C7H12O4 and a molecular weight of 160.17 g/mol.

Based on its molecular formula C7H12O4, Nitrendipine Impurity 12 contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 160.17 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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), Nitrendipine Impurity 12 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.
