4-Bromo-n-propylbenzene (1-Bromo-4-propylbenzene) is an important brominated aromatic compound widely used in organic synthesis and pharmaceutical intermediates. It exhibits a boiling point of 225°C (lit.) and density of 1.286 g/mL at 25°C, with a refractive index of n20/D 1.537. This compound is moisture-sensitive and should be stored under inert atmosphere at room temperature. Safety precautions include wearing gloves/eye protection due to potential skin/eye irritation (GHS Category 2). It serves as a key building block for liquid crystal materials and pharmaceutical active ingredients through palladium-catalyzed coupling reactions.
