Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions for the synthesis of biaryl compounds in pharmaceutical and agrochemical industries. Its aldehyde and boronic acid functional groups allow dual reactivity, enabling sequential or selective transformations in multi-step organic syntheses. Commonly employed in the development of conjugated materials for optoelectronics and organic semiconductors. Also applied in the preparation of functionalized thiophene derivatives, which are important in drug discovery and material science due to their electronic properties and structural versatility.
