Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in pharmaceutical and agrochemical synthesis. Its boronate ester group facilitates efficient and selective coupling with aryl or heteroaryl halides under palladium catalysis. Commonly employed in the preparation of biologically active compounds, including drug candidates containing pyrazole scaffolds. Suitable for use in late-stage functionalization due to its stability and reactivity profile. Also applied in materials science for constructing conjugated systems in organic electronics.
