Used as a deuterated reagent in organic synthesis, particularly in the preparation of labeled compounds for research and development. It is valuable in NMR spectroscopy studies due to its deuterium content, which helps in tracking molecular structures and reactions. Also employed in pharmaceutical research to create isotopically labeled drugs for metabolic and pharmacokinetic studies. Its bromine atom makes it a useful intermediate in cross-coupling reactions, such as Suzuki or Heck reactions, to build complex organic molecules. Additionally, it serves as a building block in material science for developing advanced polymers and functional materials.
