Used as a key intermediate in the synthesis of biologically active compounds, particularly in pharmaceutical research. It serves as a building block for kinase inhibitors, which are important in the development of anticancer agents. Its structure allows for selective modifications, enabling the creation of derivatives with potential activity against various diseases, including inflammation and neurological disorders. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to its ability to mimic purine bases in nucleotide-binding proteins.
