Chemical Structure
Description
6-Bromo-1,4-dimethyl-9h-carbazole-3-carbaldehyde (C15H12BrNO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 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).
6-Bromo-1,4-dimethyl-9h-carbazole-3-carbaldehyde (CAS 18073-21-7) is a high-purity analytical reference standard with the molecular formula C15H12BrNO and a molecular weight of 302.17 g/mol.
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), 6-Bromo-1,4-dimethyl-9h-carbazole-3-carbaldehyde 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.
