Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in Suzuki-Miyaura cross-coupling reactions where the boronic acid group enables formation of carbon-carbon bonds. Its structure supports the development of heterocyclic compounds with biological activity. Also employed in materials science for constructing conjugated organic systems in electronic devices such as organic semiconductors and sensors. The carboxylic acid functionality allows for further derivatization, enhancing its utility in combinatorial chemistry and drug discovery.
