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 creating targeted therapies. It is also employed in the preparation of agrochemicals and organic electronic materials due to its electron-deficient heterocyclic core. Commonly utilized in cross-coupling reactions such as Suzuki and Buchwald-Hartwig to build complex molecules in medicinal chemistry research.
