Used as a key intermediate in the synthesis of kinase inhibitors and antiviral agents. Commonly found in pharmaceutical research targeting cancer therapies, particularly in the development of selective inhibitors for tyrosine kinases. Also serves as a scaffold in drug discovery due to its structural similarity to purine bases, enabling interaction with biological targets such as enzymes and receptors involved in cell signaling and proliferation. Its derivatives are explored for anti-inflammatory and immunomodulatory applications.
