Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
9-(2-Bromophenyl)-3,6-di-tert-butyl-9H-carbazole (CAS 1399743-51-1), molecular formula C26H28BrN and molecular weight 434.41 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C26H28BrN, 9-(2-Bromophenyl)-3,6-di-tert-butyl-9H-carbazole contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 434.41 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
