2-Bromoiodobenzene is a versatile halogenated aromatic compound widely used in cross-coupling reactions (e.g., Suzuki, Heck reactions) for pharmaceutical and material synthesis. It exhibits a density of 2.2±0.1 g/cm³, boiling point of 249.7±13.0°C at 760 mmHg, and melting point of 9-10°C (lit.). The compound is light-sensitive and should be stored under inert gas (N₂/Ar) at 2-8°C in amber glass containers. As a bifunctional electrophile, it enables sequential functionalization of both halogens (Br/I). Safety precautions include glove/eye protection due to skin/eye irritation (GHS Category 2) and moisture sensitivity.
