Used in pharmaceutical research as a key intermediate in the synthesis of kinase inhibitors, particularly for targeting cancer-related enzymes such as JAK and SYK kinases. Its structure supports the development of small molecule drugs due to its ability to mimic purine bases, enhancing binding affinity to enzyme active sites. Also explored in the design of anti-inflammatory and neurodegenerative disease therapeutics. Commonly employed in medicinal chemistry for scaffold modification to improve drug potency and selectivity.
