Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antiviral, antibacterial, and anticancer agents. Its structure supports the design of kinase inhibitors and other bioactive molecules in medicinal chemistry, facilitating binding to biological targets such as enzymes and receptors. It is also employed in structure-activity relationship (SAR) studies to optimize efficacy and specificity of drugs. Additionally, utilized in research for fluorescent probes due to its nitrogen-rich heterocyclic framework, aiding in the study of biological systems and molecular interactions.
