Used primarily as an intermediate in the synthesis of immunomodulatory and antiviral compounds. It serves as a key scaffold in developing Toll-like receptor 7 (TLR7) and TLR8 agonists, which are important in enhancing immune responses. Found in research related to vaccine adjuvants and treatments for viral infections and certain cancers due to its ability to stimulate cytokine production. Also employed in the development of small-molecule immune activators for topical and systemic therapies.
