Used in organic synthesis as a building block for pharmaceuticals and agrochemicals, particularly in Suzuki-Miyaura cross-coupling reactions to form biaryl compounds. The aldehyde and boronic acid functional groups allow for sequential transformations, enabling the construction of complex aromatic structures. Commonly employed in the development of liquid crystals, dyes, and bioactive molecules due to its bifunctional reactivity. Also utilized in sensor design for detecting diols and carbohydrates through boronate ester formation.
