2,3,5-Tribromothiophene is a highly brominated thiophene derivative widely used as a key intermediate in organic synthesis and material science. It exhibits a melting point of 25-28°C (lit.) and boiling point of 120°C at 11 mmHg, with a density of 2.483 g/mL at 25°C. The compound's refractive index is 1.664 (n20/D) and flash point 114.5°C. As a versatile building block, it is particularly valuable for synthesizing π-conjugated polymers and organic electronic materials. Storage should be in a cool, dry place under inert atmosphere. Safety precautions are required due to its potential to cause skin/eye irritation (GHS Category 2) and release of toxic bromine compounds upon decomposition.
