n-Propylbenzene is an aromatic hydrocarbon widely used as a solvent and intermediate in organic synthesis. It has a characteristic aromatic odor with a boiling point of 159°C (lit.) and melting point of -99°C. The liquid has a density of 0.862 g/mL at 25°C and refractive index of 1.491. As a flammable liquid (Flash point 30°C), it should be stored in tightly closed containers away from heat/ignition sources. Applications include use in dye synthesis, polymer additives, and as a precursor for pharmaceuticals. Safety precautions include adequate ventilation and PPE due to potential CNS depression effects (GHS Category 3).
