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 the preparation of antitumor compounds due to its structural similarity to purine bases, allowing it to interact with enzyme active sites involved in cell proliferation. Its derivatives are explored for activity against various cancers, including breast and prostate cancer. Also utilized in research settings to design new bioactive molecules with improved selectivity and potency.
