Used in Suzuki-Miyaura cross-coupling reactions as a key building block for synthesizing complex organic molecules, particularly in pharmaceutical and agrochemical research. The masked boronic acid group enables selective coupling with aryl halides under mild conditions, while the aldehyde functionality allows further derivatization, such as condensation or reduction, enabling rapid assembly of multifunctional aromatic compounds. Its stability and dual reactivity make it valuable in medicinal chemistry for constructing biaryl scaffolds found in bioactive molecules.
