Used in organic synthesis as an intermediate for pharmaceuticals and bioactive compounds. Its structure supports the development of novel heterocyclic systems with potential activity in medicinal chemistry. Commonly employed in research settings to construct complex polycyclic frameworks, especially in the design of kinase inhibitors and fluorescent probes. Also applied in materials science for developing organic semiconductors due to its rigid, conjugated backbone. Frequently utilized in cross-coupling reactions to introduce functionalized quinoline derivatives.
