Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions for the synthesis of biaryl compounds in pharmaceutical and agrochemical research. Its aldehyde and boronate functional groups allow dual reactivity, enabling sequential or selective transformations to build complex aromatic structures. Commonly employed in the development of fluorescent probes and organic electronic materials due to its conjugated system and derivatization potential. Also applied in medicinal chemistry for constructing heterocyclic scaffolds via cyclization reactions.
