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