Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of bioactive molecules with antifungal, antibacterial, and anti-inflammatory properties. Its structure supports the construction of more complex heterocyclic compounds, making it valuable in medicinal chemistry research. Commonly employed in condensation reactions to form pyrrolo[2,3-b]pyridines and other fused ring systems with potential kinase inhibitory activity. Also applied in the preparation of fluorescent probes and organic semiconductors due to its conjugated framework and electron-rich nature.
