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 ATP-binding sites in enzymes. Its derivatives are explored for anti-inflammatory, antiviral, and antiproliferative activities. Also employed in research settings to design and optimize new drug candidates targeting neurological disorders and metabolic diseases.
