Used primarily as a key intermediate in the synthesis of complex organic molecules, especially in pharmaceuticals and agrochemicals. Its reactive bromomethylidene and bromo functionalities allow for selective cross-coupling reactions, making it valuable in constructing carbon–carbon and carbon–heteroatom bonds. Commonly employed in the development of bioactive compounds, including antifungal and anticancer agents, due to its ability to modify molecular frameworks with high specificity. Also utilized in materials science for designing functionalized polymers and specialty monomers.
