2-Chloro-3-bromothiophene is a halogenated thiophene derivative widely used as a key intermediate in pharmaceutical and agrochemical synthesis. This compound features a boiling point of 70°C at 9 mmHg and a density of 1.808 g/mL at 25°C. With limited water solubility (0.2 g/L at 20°C), it should be stored in sealed containers under inert atmosphere. The material is classified as an irritant (GHS Category 2) and requires protective gloves/eye protection during handling. Its unique halogen substitution pattern enables diverse coupling reactions in heterocyclic chemistry, particularly in the synthesis of thiophene-based bioactive molecules.
