Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in cross-coupling reactions such as Sonogashira coupling to form conjugated aryl alkynes. Its bromo and ethynyl functional groups allow for sequential functionalization, making it valuable in building complex organic molecules. Commonly employed in the development of fluorinated bioactive compounds where the fluorine atom enhances metabolic stability and binding affinity. Also applied in materials science for constructing π-conjugated systems used in organic electronics.
