Used primarily as a key intermediate in Suzuki-Miyaura cross-coupling reactions for the synthesis of biaryl compounds in pharmaceutical and agrochemical research. Its boronate ester group enables efficient carbon-carbon bond formation under mild conditions, making it valuable in the development of novel drug candidates and functional materials. Commonly employed in medicinal chemistry to introduce pyrazole-containing fragments into larger molecular architectures, enhancing biological activity or pharmacokinetic properties. Also utilized in the preparation of organic semiconductors and advanced polymers due to its stable aromatic structure and reactivity profile.
