Used in organic synthesis as an intermediate for pharmaceuticals, particularly in the development of kinase inhibitors. Its structure allows for selective cross-coupling reactions, making it valuable in constructing complex heterocyclic systems for drug discovery. Commonly employed in palladium-catalyzed reactions to introduce pyrido-pyrazine scaffolds into bioactive molecules. Also applied in the research of antitumor and antiviral compounds due to its ability to interact with biological targets involving nucleotide-binding sites.
