4-bromo-9H-carbazole(CAS: 3652-89-9)

4-bromo-9H-carbazole is a crystalline solid with a molecular weight of approximately 227.05 g/mol. It is sparingly soluble in common organic solvents like dichloromethane and acetone but insoluble in water. The compound is moderately reactive towards electrophilic aromatic substitution reactions. It is stable under normal storage conditions but may degrade under strong oxidizing or reducing conditions.

4-bromo-9H-carbazole is commonly synthesized via bromination of 9H-carbazole. The reaction is usually carried out using bromine in the presence of a Lewis acid catalyst like aluminum bromide. The yield is typically high, with good selectivity towards the brominated product.

4-bromo-9H-carbazole is used in various industries, including pharmaceuticals, where it serves as a precursor for drug synthesis, and in polymers, where it can be incorporated into materials for specific properties. It is also used in sensors and semiconductors due to its unique electronic properties.

When handling 4-bromo-9H-carbazole, it is important to use appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. It should be handled in a well-ventilated area or a fume hood to minimize inhalation risks. Spills should be cleaned up with care, and the Material Safety Data Sheet (MSDS) should be consulted for detailed spill procedures.
