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 to introduce the isonicotinate core into target molecules. Also utilized in agrochemical research for designing new pesticides and herbicides due to its halogenated pyridine scaffold, which enhances binding affinity and metabolic stability.
