Used in pharmaceutical research as a key intermediate in the synthesis of kinase inhibitors, particularly in the development of anticancer agents. Its structure allows for selective binding to enzyme active sites, making it valuable in designing drugs that target specific signaling pathways in tumor cells. Also explored in the study of nucleotide analogs for antiviral applications due to its pyrimidine core, which mimics natural nucleobases. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies to optimize drug potency and selectivity.
