Chemical Structure

3,6-Dibromo-9-(naphthalen-2-yl)-9H-carbazole CAS 1221237-83-7 chemical structure

Description

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.

3,6-Dibromo-9-(naphthalen-2-yl)-9H-carbazole (CAS 1221237-83-7) is a high-purity analytical reference standard with the molecular formula C22H13Br2N and a molecular weight of 451.15 g/mol.

3,6-Dibromo-9-(naphthalen-2-yl)-9H-carbazole (C22H13Br2N) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
