Used as a key reagent in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds between aromatic systems. Its primary application lies in organic synthesis, particularly in the preparation of conjugated organic materials such as semiconductors, OLEDs, and pharmaceutical intermediates. The compound acts as a boronic ester derivative, offering enhanced stability and reactivity with halogenated arenes in the presence of palladium catalysts. It is especially valuable in the synthesis of thiophene-based functional molecules for electronic and optoelectronic devices.
