Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 389.04 g/mol gives Procaterol Impurity 5 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Procaterol Impurity 5 (CAS CATO-C4X-18105) is a certified pharmaceutical impurity reference standard with the molecular formula C13H11Br2NO3 and a molecular weight of 389.04 g/mol.
Based on its molecular formula C13H11Br2NO3, Procaterol Impurity 5 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 389.04 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), Procaterol Impurity 5 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.
