Used primarily in research settings as an intermediate in the synthesis of biologically active compounds, particularly in the development of kinase inhibitors and other pharmaceutical agents targeting cellular signaling pathways. Its structure supports derivatization for use in medicinal chemistry, enabling the exploration of drug candidates with potential antiviral, anticancer, or anti-inflammatory properties. Also employed in the study of pteridine-based metabolic processes due to structural similarity to cofactors involved in redox reactions.
