Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions, enabling the synthesis of complex organic molecules, particularly in pharmaceutical and agrochemical industries. Its aldehyde and boronate functional groups allow dual reactivity, making it valuable for constructing biaryl compounds and conjugated systems in materials science, including organic semiconductors and fluorescent dyes. Commonly employed in the development of sensors and optoelectronic devices due to its ability to form extended π-conjugated structures.
