Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and antitumor agents. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for constructing biologically active molecules. Commonly employed in cross-coupling reactions, such as Suzuki and Heck reactions, to introduce aryl or vinyl groups in drug candidates. Also utilized in agrochemical research for designing new active ingredients with improved efficacy and selectivity.
