5-Bromobenzo[b]thiophene is a halogenated heterocyclic compound widely used as a key intermediate in pharmaceutical synthesis, particularly for antitumor and antiviral agents. It exhibits a melting point of 47-48°C and boiling point of 105-107°C (10 mmHg), with a density of 1.649 g/cm³. The compound is light-sensitive and should be stored sealed in dark containers at 2-8°C. Its bromine substitution at the 5-position enables diverse cross-coupling reactions (e.g., Suzuki, Stille). Safety precautions include wearing gloves/eye protection due to potential skin/eye irritation (GHS Category 2).
