Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of antiviral and antibacterial agents. Its structure allows for selective functionalization, making it valuable in constructing nitrogen-containing heterocycles. Commonly employed in medicinal chemistry for building blocks in drug discovery programs, especially in the design of kinase inhibitors and other bioactive molecules. Also utilized in research settings for the preparation of fluorescent probes and organic semiconductors due to its electron-deficient aromatic core.
