Dibromochloromethane is a colorless to yellow, heavy and nonflammable compound with formula CHBr₂Cl. It is a trihalomethane. The substance has a sweet odour. Small quantities of dibromochloromethane are produced in ocean by algae.

Applications

Dibromochloromethane was formerly used as a flame retardant and as an intermediate in chemicals manufacturing. Today it is used only as a laboratory reagent. Dibromochloromethane is also a disinfection byproduct, formed by the reaction of chlorine with natural organic matter and bromide ions in the raw water supply. As a result, it is commonly found in chlorinated drinking water. Also, it is able to reduce methane production in ruminants by 79 %
