CATO supplies 9-(4-Chloro-6-phenyl-1,3,5-triazin-2-yl)-9H-carbazole (CAS 1268244-56-9), a certified reference material (molecular formula C21H13ClN4, MW 356.81 g/mol) for analytical method development and quality control.
Based on its molecular formula C21H13ClN4, 9-(4-Chloro-6-phenyl-1,3,5-triazin-2-yl)-9H-carbazole 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 356.81 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), 9-(4-Chloro-6-phenyl-1,3,5-triazin-2-yl)-9H-carbazole 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.
