Chemical Structure
Description
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
CATO supplies 9-([1,1'-biphenyl]-4-yl)-3,6-dibromo-9h-carbazole (CAS 894791-50-5), a certified reference material (molecular formula C24H15Br2N, MW 477.19 g/mol) for analytical method development and quality control.
9-([1,1'-biphenyl]-4-yl)-3,6-dibromo-9h-carbazole (C24H15Br2N) 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.
