Used in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions, to create complex molecules for pharmaceuticals and materials science. Acts as a key intermediate in constructing heterocyclic compounds, which are essential in drug development. Also employed in the production of organic electronic materials, such as semiconductors and light-emitting diodes (LEDs), due to its ability to form stable conjugated systems. Its boronic ester group enhances reactivity and selectivity in coupling reactions, making it valuable in designing advanced polymers and small molecules for optoelectronic applications.
