Chemical Structure

Arbidol Impurity 38 CAS CATO-C4X-112938 chemical structure

Description

CATO supplies Arbidol Impurity 38 (CAS CATO-C4X-112938), a pharmacopoeial impurity reference standard (molecular formula C11H12BrNO, MW 254.12 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C11H12BrNO, Arbidol Impurity 38 contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 254.12 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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), Arbidol Impurity 38 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.
