n-Butylbenzene is an aromatic hydrocarbon solvent widely used in organic synthesis and as a reference standard in analytical chemistry. It has a characteristic boiling point of 183°C, flash point of 59°C (closed cup), and density of 0.86 g/cm³ at 25°C. The compound is miscible with common organic solvents but insoluble in water. Storage should be in tightly sealed containers away from ignition sources. Safety precautions include adequate ventilation due to flammability (GHS Category 3) and potential eye/skin irritation (GHS Category 2).
