Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and fine chemicals. Its bromine functionality allows for further substitution reactions, such as nucleophilic displacement or coupling reactions, enabling the extension of carbon chains or introduction of functional groups. Commonly employed in the development of bioactive molecules, including potential drug candidates, due to its ability to act as a building block in complex molecular architectures. Also utilized in polymer chemistry for modifying polymer side chains or creating functionalized precursors.
