Used primarily in organic synthesis as a key building block for Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in the development of complex aromatic frameworks. Its boronate ester functionality allows for efficient coupling with aryl halides, making it valuable in the preparation of conjugated polymers, pharmaceuticals, and advanced materials. The ester groups can be hydrolyzed or further modified post-coupling, offering additional synthetic versatility for constructing functionalized terephthalate derivatives used in metal-organic frameworks (MOFs) or optoelectronic materials.
