Used primarily in Suzuki-Miyaura cross-coupling reactions, this compound serves as a key boronic ester reagent in the synthesis of complex organic molecules, especially in pharmaceuticals and agrochemicals. Its phenolic and methoxy groups enhance stability and direct regioselective coupling, making it valuable in creating biaryl structures found in active drug components. It is also employed in materials science for constructing conjugated systems in organic electronics, such as OLEDs and semiconducting polymers. The presence of the boronate ester allows for mild, efficient coupling under palladium catalysis, which is compatible with a wide range of functional groups.
