Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other biologically active compounds. Its structure allows for selective functionalization, making it valuable in creating targeted drug candidates. Commonly employed in cross-coupling reactions, such as Sonogashira coupling, to build complex heterocyclic systems found in medicinal chemistry. Also utilized in agrochemical research for designing novel pesticides and herbicides due to its ability to enhance binding affinity and metabolic stability.
