Used in organic synthesis as a key intermediate for pharmaceuticals and agrochemicals. Its aldehyde and boronic acid functional groups allow participation in cross-coupling reactions, particularly Suzuki-Miyaura coupling, enabling the construction of biaryl structures. Commonly employed in the development of sensors and probes due to its ability to bind diols and form stable cyclic esters, useful in glucose detection and carbohydrate recognition. Also applied in the synthesis of covalent organic frameworks (COFs) and other porous materials for catalysis and sensing applications. Its phenolic hydroxyl group enhances solubility and provides a site for further derivatization in drug design.
