Uses

Bromine monochloride is used in analytical chemistry in determining low levels of mercury, to quantitatively oxidize mercury in the sample to Hg(II) state.

Bromine monochloride is used as a biocide, specifically as an algaecide, fungicide, and disinfectant, in industrial recirculating cooling water systems.

Addition of bromine monochloride is used in some types of Li-SO2 batteries to increase voltage and energy density.[2]
