Application

(3-Ethoxycarbonylphenyl)boronic acid is widely used as a coupling partner in Suzuki-Miyaura reactions to form biaryl compounds, a critical step in drug discovery and material science. Its boronic acid moiety enables efficient cross-coupling with aryl halides under palladium catalysis, facilitating the synthesis of complex organic frameworks. Researchers also employ it in the development of sensors and catalysts due to its ability to form reversible covalent bonds with diols and other Lewis bases.
