Used as a key building block in Suzuki-Miyaura cross-coupling reactions, enabling the synthesis of conjugated organic materials for applications in organic electronics such as organic light-emitting diodes (OLEDs), organic photovoltaics (OPVs), and conductive polymers. Its boronic ester group facilitates efficient carbon-carbon bond formation with aryl halides, making it valuable in pharmaceutical and agrochemical research for constructing complex thiophene-based structures. The carboxylic acid functionality allows for further derivatization or attachment to surfaces and macromolecules, expanding its utility in material science and bioconjugation.
