Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and antiviral agents. Its structure allows for easy functionalization, making it valuable in medicinal chemistry for building bioactive molecules. It is also employed in the preparation of agrochemicals, including herbicides and fungicides, due to its ability to enhance binding selectivity in active ingredients. Additionally, it serves as a building block in the creation of fluorescent probes and optoelectronic materials, where its electron-withdrawing and hydrogen-bonding properties improve performance.
