Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 256.09 g/mol gives Irsogladine Impurity 7 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Irsogladine Impurity 7 (CAS CATO-C4X-29147), a pharmacopoeial impurity reference standard (molecular formula C9H7Cl2N5, MW 256.09 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C9H7Cl2N5, Irsogladine Impurity 7 contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 256.09 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), Irsogladine Impurity 7 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.
