IBR2 is widely used in organic synthesis as a brominating agent, particularly in the addition of bromine to alkenes and alkynes to form dibromo compounds. It is also employed in the bromination of aromatic compounds, where it facilitates the introduction of bromine atoms into the aromatic ring. In pharmaceutical research, IBR2 is utilized in the preparation of brominated intermediates, which are crucial for the development of various drugs. Additionally, it finds application in the synthesis of agrochemicals, where brominated compounds play a significant role in creating effective pesticides and herbicides. Its reactivity and efficiency make it a valuable reagent in industrial and laboratory settings for producing brominated organic molecules.
