Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for creating analogs with improved biological activity. Commonly employed in cross-coupling reactions to introduce aryl or heteroaryl groups, enhancing molecular diversity in drug discovery programs. Also utilized in the preparation of agrochemicals due to its stability and reactivity profile in heterocyclic transformations.
