Compared with other compounds in its class, the molecular weight of 324.25 g/mol gives Trazodone Impurity 34 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Trazodone Impurity 34 (CAS CATO-C4X-177234) is a certified pharmaceutical impurity reference standard with the molecular formula C16H19Cl2N3 and a molecular weight of 324.25 g/mol.
Based on its molecular formula C16H19Cl2N3, Trazodone Impurity 34 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 324.25 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), Trazodone Impurity 34 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.
