Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in medicinal chemistry due to its ability to form hydrogen bonds and participate in π-π stacking interactions, enhancing binding affinity to biological targets. Also employed in the preparation of agrochemicals and functional materials, such as organic semiconductors, where its heterocyclic structure contributes to electronic properties. Its reactivity allows for easy functionalization, making it valuable in combinatorial chemistry and high-throughput screening for drug discovery.
