Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions for the synthesis of conjugated organic materials, particularly in the development of pharmaceuticals and functionalized thiophene derivatives. Its boronic ester group enables efficient carbon-carbon bond formation under mild conditions, making it valuable in drug discovery and the preparation of π-conjugated systems for organic electronics. The methoxycarbonyl group enhances solubility and directs regioselectivity during coupling, improving reaction efficiency. Commonly employed in the construction of biaryl structures found in bioactive molecules and advanced materials.
