Used in organic synthesis as a key intermediate for the preparation of complex molecules, particularly in the development of pharmaceuticals and agrochemicals. It serves as a versatile building block in cross-coupling reactions, such as Suzuki-Miyaura coupling, to create biaryl compounds. Its boronate ester group enhances reactivity and selectivity in these transformations. Additionally, it is employed in the synthesis of organic materials, including polymers and ligands for catalysis, due to its ability to introduce aldehyde functional groups into molecular structures. Its applications extend to the field of materials science, where it contributes to the development of advanced organic frameworks and functionalized surfaces.
