1,2-Dibromoethylbenzene (also known as styrene dibromide) is an organobromine compound primarily used as a flame retardant intermediate and in organic synthesis. It exhibits a melting point of 70-74°C (lit.) and boiling point of 139-141°C at 15 mmHg, with a density of 1.74 g/cm³. The compound is soluble in organic solvents like ethanol and benzene but insoluble in water. As a reactive dibromide, it participates in various coupling reactions and serves as a precursor for polymer modifications. Storage should be in dark, sealed containers at room temperature due to light sensitivity. Safety precautions include skin/eye protection (GHS Category 2) and avoiding inhalation of dust.
