Used primarily in pharmaceutical research as an intermediate in the synthesis of biologically active compounds, particularly those targeting immune modulation. It serves as a key scaffold in the development of Toll-like receptor (TLR) agonists, especially TLR7 and TLR8, which are important in vaccine adjuvants and cancer immunotherapies. Its structure supports the design of small molecule drugs that enhance immune response by stimulating cytokine production. Due to its reactivity and functional groups, it is also employed in medicinal chemistry for constructing nitrogen-rich heterocyclic systems in drug discovery programs.
