Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 234.05 g/mol gives 8-Bromoquinoxaline-5-carbonitrile distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
8-Bromoquinoxaline-5-carbonitrile (CAS 2101944-52-7), molecular formula C9H4BrN3 and molecular weight 234.05 g/mol, is a CATO reference standard with documented purity and traceability.
8-Bromoquinoxaline-5-carbonitrile (C9H4BrN3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 8-Bromoquinoxaline-5-carbonitrile 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.
