Used in pharmaceutical research as a key intermediate in the synthesis of bioactive compounds, particularly in the development of kinase inhibitors. Shows potential in medicinal chemistry for targeting cancer-related enzymes due to its ability to interact with ATP-binding sites. Also employed in the design of fluorescent probes for cellular imaging, leveraging its rigid aromatic structure and favorable photophysical properties. Its amide and amino functional groups allow for easy derivatization, making it valuable in structure-activity relationship (SAR) studies.
