Chemical Structure

Rupatadine Impurity 24 CAS 100910-66-5 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.

Rupatadine Impurity 24 (CAS 100910-66-5) is a certified pharmaceutical impurity reference standard with the molecular formula C7H7NO and a molecular weight of 121.14 g/mol.

Based on its molecular formula C7H7NO, Rupatadine Impurity 24 contains an amide group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 121.14 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).

As a certified reference material (CRM), Rupatadine Impurity 24 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.
