Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions for the synthesis of conjugated organic materials. It is particularly valuable in the preparation of organic semiconductors, liquid crystals, and fluorescent dyes due to its vinyl-linked phenolic structure that enhances electronic properties. The boronate ester group enables efficient carbon-carbon bond formation under mild conditions, making it suitable for constructing complex aromatic systems in pharmaceuticals and advanced materials. Its phenolic hydroxyl group allows for further functionalization, such as protection/deprotection strategies or attachment to polymers and surfaces, expanding its utility in material science and medicinal chemistry.
