Used primarily as a biocide and preservative in industrial water systems, this compound effectively controls microbial growth in paper mills, cooling towers, and metalworking fluids. Its strong bromine-based reactivity makes it effective against bacteria, fungi, and algae, helping prevent biofouling and spoilage. It is also employed as an intermediate in organic synthesis for introducing bromine in pharmaceutical and agrochemical manufacturing. Due to its reactivity and potential toxicity, it is handled under controlled conditions in industrial settings.
