Used as a key intermediate in the synthesis of various pharmaceuticals, particularly in the development of antiviral and anticancer agents. Its structure allows for easy functionalization, making it valuable in creating nitrogen-rich heterocyclic compounds. Commonly employed in medicinal chemistry for building blocks in drug design, especially in kinase inhibitors and other bioactive molecules. Also utilized in the preparation of fluorescent dyes and optoelectronic materials due to its electron-deficient aromatic system.
