3-Bromo-9-(naphthalen-2-yl)-9H-carbazole(CAS: 934545-80-9)

3-Bromo-9-(naphthalen-2-yl)-9H-carbazole is a crystalline solid with a molecular weight of approximately 304.26 g/mol. It has limited water solubility and is more soluble in organic solvents like dichloromethane and dimethylformamide. Chemically, it exhibits typical carbazole reactivity, such as nucleophilic and electrophilic substitution, and is stable under normal conditions but can react with strong bases or acids. Its physical properties include a melting point of around 240°C.

3-Bromo-9-(naphthalen-2-yl)-9H-carbazole can be synthesized via the coupling of 2-bromo-9H-carbazole and 2-naphthylamine under basic conditions, typically using potassium carbonate as a catalyst. The reaction is performed in an aprotic solvent such as N,N-dimethylformamide (DMF) at elevated temperatures. The yield is generally high, and the product can be isolated by recrystallization.

3-Bromo-9-(naphthalen-2-yl)-9H-carbazole is used in various industries, particularly in the pharmaceutical sector for drug synthesis, and in the semiconductor industry for organic thin-film transistors and organic light-emitting diodes (OLEDs). It is also utilized in the development of sensors and polymers due to its unique electronic properties.

When handling 3-Bromo-9-(naphthalen-2-yl)-9H-carbazole, proper personal protective equipment (PPE) should be worn, including gloves, goggles, and a lab coat. The material should be handled in a well-ventilated area or a fume hood to avoid inhalation. Spills should be cleaned up immediately using appropriate absorbents, and the area should be thoroughly washed down. Always refer to the safety data sheet (SDS) for detailed handling instructions and emergency procedures.
