Used primarily as an intermediate in organic synthesis, especially in cross-coupling reactions such as Sonogashira coupling, to introduce aryl or alkynyl groups into more complex molecules. Its bromo and alkyne functionalities make it a versatile building block in pharmaceutical and agrochemical synthesis. The compound is also employed in the development of conjugated materials for electronic applications, including organic semiconductors and fluorescent probes. Due to the presence of halogen atoms, it participates in metal-catalyzed reactions to form carbon–carbon bonds efficiently, supporting the construction of advanced aromatic and heteroaromatic systems.
