Description
Compared with other compounds in its class, the molecular weight of 277.75 g/mol gives 9-(4-Chlorophenyl)-9H-carbazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
9-(4-Chlorophenyl)-9H-carbazole (CAS 19264-71-2) is a high-purity analytical reference standard with the molecular formula C18H12ClN and a molecular weight of 277.75 g/mol.
9-(4-Chlorophenyl)-9H-carbazole (C18H12ClN) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine 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), 9-(4-Chlorophenyl)-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.
