Used as a key intermediate in the synthesis of pharmaceuticals, 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 involved in cell signaling. Commonly employed in the design of antitumor, antiviral, and anti-inflammatory agents. Its derivatization allows fine-tuning of pharmacokinetic properties, enhancing drug efficacy and selectivity.
