Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of compounds with potential antiviral and anticancer properties. It serves as a building block in medicinal chemistry due to its structural similarity to purine bases, enabling incorporation into molecules that interact with biological targets such as enzymes and receptors. Also explored in the design of kinase inhibitors and antimicrobial agents. Its derivatives are investigated for improved bioavailability and target selectivity in drug candidates.
