2-Formylphenylboronic acid is primarily used as a key intermediate in the synthesis of biaryl compounds via Suzuki-Miyaura cross-coupling reactions. It serves as a precursor for the development of pharmaceuticals, agrochemicals, and functional materials. The formyl group allows for further derivatization, enabling the creation of complex molecular architectures. Its reactivity is also leveraged in sensor development and boronic acid-based recognition systems. Suitable for use in both academic and industrial research settings.
