Widely used in organic synthesis as a key intermediate for constructing complex molecules, especially in pharmaceutical and agrochemical research. Its primary application lies in its ability to act as a bifunctional coupling partner in palladium-catalyzed reactions, such as Suzuki-Miyaura and Heck couplings, enabling the formation of extended aromatic systems and heterocycles. The silyl-protected diol structure allows for selective deprotection, making it valuable in stepwise synthesis where orthogonal protection strategies are required. It is also employed in the preparation of conjugated materials for organic electronics, including semiconductors and luminescent compounds, due to its stability and reactivity profile in cross-coupling processes.
