Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of immunomodulatory agents. It serves as a key scaffold in the creation of small molecule drugs that stimulate the immune system, especially through activation of Toll-like receptors (TLR), such as TLR7 and TLR8. These receptors play a critical role in antiviral and antitumor immune responses. Derivatives of this compound are investigated for use in treating viral infections, certain cancers, and as vaccine adjuvants to enhance immune response. Its structure allows for modification to optimize potency, selectivity, and pharmacokinetic properties in drug design.
