Used as a selective brominating agent in organic synthesis, particularly for the bromination of aromatic compounds and alkenes under mild conditions. It serves as a stable and easy-to-handle source of positive bromine (Br⁺), making it effective for electrophilic bromination reactions. Commonly applied in the preparation of brominated intermediates in pharmaceuticals, agrochemicals, and fine chemicals. Its solubility in polar solvents and controlled reactivity reduce the formation of polybrominated by-products, enhancing reaction selectivity. Also utilized in analytical chemistry for bromine transfer in qualitative tests.
