Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly kinase inhibitors. It plays an important role in the development of targeted cancer therapies due to its ability to selectively modify enzyme activity involved in cell signaling pathways. Its structure allows for functionalization at multiple sites, making it valuable in medicinal chemistry for optimizing drug potency and selectivity. Also employed in the preparation of biologically active molecules in research settings, especially in the design of antitumor and anti-inflammatory agents.
