Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other bioactive molecules. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for constructing complex heterocyclic compounds. Commonly employed in cross-coupling reactions to introduce the isonicotinic core into target molecules, especially in the research of anticancer and anti-inflammatory agents. Also utilized in agrochemical research for designing new active ingredients due to its favorable reactivity and stability in multi-step syntheses.
