Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and antiviral agents. It serves as a building block in heterocyclic chemistry, enabling the construction of fused pyrazole derivatives with biological activity. Commonly employed in medicinal chemistry for structure-activity relationship studies due to its ability to form hydrogen bonds and participate in π-π interactions. Also applied in the preparation of agrochemicals and functional materials where nitrogen-rich scaffolds are required.
