Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of nicotinamide-based drugs and kinase inhibitors. It serves as a building block in medicinal chemistry due to the reactivity of both the cyano and iodo functional groups, allowing for selective cross-coupling reactions such as Suzuki or Buchwald-Hartwig aminations. Commonly employed in the preparation of bioactive molecules and heterocyclic compounds with potential applications in treating inflammatory diseases, cancer, and neurological disorders. Also utilized in agrochemical research for developing novel pesticides and herbicides. Its structural features make it valuable in materials science for constructing nitrogen-rich organic frameworks.
