Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in medicinal chemistry due to its structural similarity to purine bases, enabling interactions with biological targets such as enzymes and receptors. Its derivatives are explored for anti-inflammatory, antiviral, and neuroprotective activities. Commonly employed in research settings to design small molecule therapeutics targeting central nervous system disorders and oncology.
