Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in medicinal chemistry due to its nitrogen-rich heterocyclic structure, which enhances binding affinity to biological targets. Also employed in the preparation of fluorescent probes and optoelectronic materials owing to its conjugated aromatic system. Its derivatives show potential in antimicrobial and antiviral research, making it valuable in drug discovery and biochemical assays.
