Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of kinase inhibitors for targeted cancer therapies. Its structure supports binding to specific enzyme active sites, enhancing selectivity and potency. Also employed in research for antiviral compounds due to its ability to mimic purine moieties in nucleotide analogs. Commonly utilized in medicinal chemistry for scaffold modification to improve pharmacokinetic properties such as solubility and metabolic stability.
