4-Bromoethylbenzene (p-Bromoethylbenzene) is a versatile brominated aromatic compound widely used as a key intermediate in liquid crystal and pharmaceutical synthesis. This liquid exhibits a boiling point of 204.6±9.0°C at 760 mmHg and density of 1.343 g/mL at 25°C (lit.), with a refractive index of 1.544. It is insoluble in water but miscible with common organic solvents. The compound should be stored sealed in dry conditions below 30°C. Safety precautions include wearing protective gloves/eyewear due to its irritating properties (GHS Category 2). Its reactive benzylic position enables diverse transformations in organic synthesis, particularly for preparing functionalized ethylbenzene derivatives.
