Used primarily 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 mild and selective coupling with aryl or heteroaryl halides, making it valuable in constructing complex nitrogen-containing heterocycles. Commonly applied in the development of active pharmaceutical ingredients (APIs) where pyrazole motifs are required for biological activity. Also employed in materials science for synthesizing organic semiconductors and functional molecules due to its stability and reactivity profile.
