Documented Uses

• Chemical reagent/intermediate in organic synthesis.
• Dibromochloromethane exposition occurs by drinking water that has been treated with chlorine, at a swimming pool, by breathing bromoform or dibromochloromethane that has evaporated into the air, or by uptake from the water through the skin. Neither dibromochloromethane nor bromoform are likely to be found in food. (L1173)
