Betahistine Impurity 4 CAS 5344-27-4 chemical structure

Description

CATO supplies Betahistine Impurity 4 (CAS 5344-27-4), a pharmacopoeial impurity reference standard (molecular formula C7H9NO, MW 123.15 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C7H9NO, Betahistine Impurity 4 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 123.15 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), Betahistine Impurity 4 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.
