Used primarily as an intermediate in the synthesis of pharmaceuticals and agrochemicals. It plays a role in the production of certain disinfectants and biocides due to its reactive halogen content. Also utilized in water treatment as an antimicrobial agent, particularly in industrial systems to control microbial growth in cooling towers and process water. Its high reactivity makes it effective in forming other brominated compounds used in flame retardants and specialty chemicals. Handling requires caution due to its corrosive and toxic nature.
