Used in Suzuki-Miyaura cross-coupling reactions to synthesize biaryl compounds, which are key structural motifs in pharmaceuticals and agrochemicals. Its boronic acid group enables efficient carbon-carbon bond formation under mild conditions. Commonly applied in drug discovery for building conjugated systems and heterocyclic frameworks. Also utilized in materials science for creating organic semiconductors and fluorescent dyes due to its aromatic and electron-rich thiophene core. Stable and compatible with a variety of functional groups, making it suitable for complex molecule synthesis.
