Used in organic synthesis as a key intermediate for constructing complex molecules, particularly in Suzuki-Miyaura cross-coupling reactions. It plays a significant role in the development of pharmaceuticals, agrochemicals, and functional materials. The formyl and boronic acid groups make it versatile for further functionalization, enabling the creation of bioactive compounds or advanced polymers. Its application extends to materials science, where it contributes to the design of sensors or catalysts due to its reactive sites.
