Insoluble in water. Soluble in ether, chloroform and ethanol.


Carbon tetrabromide is widely utilized as a solvent for greases, waxes and oils. In Appel reaction, it is used to convert alcohols to alkyl bromides. It has the property of non-flammability and finds application in fire-resistant chemicals as an active ingredient. It is also used for separating minerals. It can serves as an intermediate in manufacturing agrochemicals. It plays a vital role in the plastic and rubber industries for blowing and vulcanization.


Store in cool place. Incompatible with strong oxidizing agents, strong bases and lithium.
