Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 322.20 g/mol gives 3-Bromo-9-phenylcarbazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-Bromo-9-phenylcarbazole (CAS 1153-85-1), molecular formula C18H12BrN and molecular weight 322.20 g/mol, is a CATO reference standard with documented purity and traceability.
3-Bromo-9-phenylcarbazole (C18H12BrN) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), 3-Bromo-9-phenylcarbazole 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.
