Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and antiviral agents. Its structure supports the formation of biologically active molecules by serving as a building block in heterocyclic chemistry. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to its ability to enhance binding affinity and metabolic stability. Also utilized in the preparation of agrochemicals and functional materials where nitrogen-containing heterocycles are required.
