Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions, enabling the synthesis of biaryl compounds important in pharmaceuticals and agrochemicals. Its aldehyde and boronate functional groups allow dual reactivity, making it valuable in multi-step organic synthesis, particularly for constructing complex aromatic molecules. Commonly employed in the development of organic electronic materials and liquid crystals due to its ability to form conjugated systems. Also utilized in the preparation of fluorescent probes and sensors, where the aldehyde group can be further modified for targeting specific analytes.
