용도

1,2-dibromotetrachloroethane is used as a fire-proofing agent. It is actively involved in the conversion of sulfones to alkenes by Ramberg-Backlund rearrangement. It is an effective replacement for ozone depleting solvents like dibromodifluoromethane and tetrabromodifluoroethane. It is also utilized as a brominating reagent. In analytical chemistry, it is used in quantitative determination of perhalogenated compounds by high-performance liquid chromatography (HPLC).

참고

Keep container tightly closed in a dry and well-ventilated place. Incompatible with strong oxidizing agents.
