Used as a key intermediate in organic synthesis, particularly in click chemistry reactions due to the azide group. It enables the formation of 1,2,3-triazoles through copper-catalyzed azide-alkyne cycloaddition (CuAAC), useful in pharmaceutical and agrochemical research. The bromine atom allows further functionalization via nucleophilic substitution, making it valuable for building complex molecules. Also employed in polymer chemistry to introduce azide functionality into polymer chains for crosslinking or modification. Its bifunctional nature supports use in linker or spacer construction in drug design and bioconjugation.
