Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in pharmaceutical and agrochemical synthesis. Its pyrazole ring and boronate ester group make it valuable for constructing biologically active molecules, particularly in drug discovery. The ethyl ester functionality allows for further chemical modifications, such as hydrolysis or amidation, to tune solubility or reactivity in multistep organic syntheses. Commonly employed in the development of kinase inhibitors and other heterocyclic compounds with therapeutic potential.
