Used primarily in organic synthesis as an intermediate for pharmaceuticals and biologically active compounds. It serves as a building block in the preparation of kinase inhibitors and other medicinal agents targeting cancer and inflammatory diseases. Its structure supports conjugation in heterocyclic systems, making it valuable in the development of nitrogen-containing rings found in many drug molecules. Also employed in research settings for creating fluorescent probes due to its ability to participate in condensation reactions and form extended pi-conjugated systems.
