Used as a reagent in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in organic synthesis. Its stability and solubility profile make it suitable for constructing biaryl compounds, especially in pharmaceutical and agrochemical research where 2-carboxyphenyl-substituted aromatic structures are needed. The carboxylic acid functionality allows for further derivatization or conjugation, adding versatility in multi-step syntheses.
