| | 3-Bromo-9H-carbazole Usage And Synthesis |
| Chemical Properties | White to light yellow solid | | Uses | 3-Bromo-9H-carbazole is an aryl hydrocarbon receptor agonist. A standard for environmental testing and research. Substance for the bological potency study, characterization of mono to tetra-halogenated carbazoles. | | Uses | 3-Bromocarbazole is used as a intermediate for organic light-emitting diode(OLED) and pharmaceutical. | | Preparation | 3-Bromocarbazole synthesis: A solution of N-bromosuccinimide (1.1g, 5.98mmol) in dimethylformamide was added dropwise to a solution of carbazole (1, 1g, 5.96mmol) in dimethylformamide (15mL) at 0°C. The reaction mixture was then stirred at room temperature for 24h. The reaction was poured into distilled water to give a cream coloured precipitate. The precipitate was filtered off under vacuum and washed with distilled water (3 × 20mL). The precipitate was dissolved in ethyl acetate, dried with sodium sulfate and filtered. Upon concentration under reduced pressure the crude product was obtained as a brown solid. After crystallisation of the crude product with chloroform, the pure 3-Bromo-9H-carbazole(692 mg, 47%) was obtained as white crystals. Rf (ethyl acetate/hexane, 1:6 v/v): 0.43; melting point: 200–201°C. |
