Used in organic synthesis as a key intermediate for pharmaceuticals and biologically active compounds. Its conjugated structure makes it valuable in the development of nitrogen-containing heterocyclic systems, particularly in the design of kinase inhibitors and antimicrobial agents. Commonly employed in condensation reactions to form fused pyrazine derivatives with potential therapeutic applications. Also utilized in materials science for constructing fluorescent probes due to its strong electron-donating and light-emitting properties under UV excitation.
