Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 325.00 g/mol gives 1,3-Dibromo-9H-carbazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 1,3-Dibromo-9H-carbazole (CAS 105908-73-4), a certified reference material (molecular formula C12H7Br2N, MW 325.00 g/mol) for analytical method development and quality control.
1,3-Dibromo-9H-carbazole (C12H7Br2N) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 1,3-Dibromo-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.
