Used primarily as a brominating agent in organic synthesis, it facilitates the addition of bromine atoms to various substrates, particularly in the bromination of alkenes, alkynes, and aromatic compounds. It is also employed in the preparation of bromo derivatives of organic molecules, which are intermediates in the synthesis of pharmaceuticals, agrochemicals, and other fine chemicals. Additionally, it serves as a catalyst or reagent in certain oxidation reactions and is valued for its selectivity and efficiency in introducing bromine into complex molecular structures.
