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 scaffold in medicinal chemistry due to its structural similarity to purine bases, enabling interaction with biological targets such as enzymes and receptors. Commonly employed in research for designing drugs with antiviral, anti-inflammatory, and antiproliferative activities. Its derivatives are explored in targeted therapies for oncology and autoimmune diseases.
