Used primarily in cross-coupling reactions, this compound serves as a key intermediate in the synthesis of pharmaceuticals and agrochemicals. Its boronate ester group enables Suzuki-Miyaura coupling, allowing efficient formation of carbon-carbon bonds with aryl or heteroaryl halides under palladium catalysis. This makes it valuable in constructing complex nitrogen-containing heterocycles found in bioactive molecules. Due to the methylsulfonyl group's electron-withdrawing properties, it enhances the stability and reactivity profile in such transformations. It is especially useful in medicinal chemistry for rapid diversification of pyrazole-based scaffolds.
