Used primarily as an intermediate in organic synthesis, especially in the pharmaceutical and agrochemical industries. It serves as a building block for the preparation of various biologically active compounds, including drugs and pesticides. Its reactive bromine groups allow for selective substitutions, making it valuable in constructing complex molecules. Commonly employed in the synthesis of benzodiazepines and other heterocyclic compounds. Also utilized in cross-coupling reactions to form carbon-carbon bonds under palladium catalysis. Its versatility in functional group transformations makes it a key reagent in research and development laboratories.
