3,4-Dibromothiophene is a brominated heterocyclic compound widely used as a key intermediate in organic synthesis, particularly for pharmaceutical and materials science applications. This liquid exhibits a boiling point of 221-222°C (lit.) and melting point of 4-5°C, with a density of 2.188 g/mL at 25°C. It serves as a crucial building block for conjugated polymers and organic electronic materials. The compound should be stored in dark, sealed containers at room temperature due to light sensitivity. Safety precautions include wearing protective gloves and eye/face protection (GHS Category 2). Its unique structure enables diverse cross-coupling reactions in thiophene chemistry.
