Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in medicinal chemistry due to its ability to mimic purine structures, enabling interactions with biological targets such as ATP-binding sites in enzymes. Its scaffold is explored in research for anti-inflammatory, antiviral, and neurodegenerative disease applications. Also employed in the design of small molecule drugs where nitrogen-rich heterocycles enhance binding affinity and selectivity.
