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 medicinal chemistry for building complex heterocyclic systems. Commonly employed in cross-coupling reactions such as Suzuki and Heck reactions to introduce the nicotinyl core into target molecules. Also utilized in agrochemical research for designing new crop protection agents due to its halogenated aromatic framework.
