Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. It serves as a core structure in compounds that modulate immune responses and exhibit antiviral activity. Its derivatives are investigated for use in dermatological treatments, including topical agents for skin conditions like actinic keratosis and basal cell carcinoma. Also employed in research settings to develop toll-like receptor (TLR) agonists, which enhance immune system activation in therapeutic vaccines and immunotherapies.
