Used in medicinal chemistry as a key intermediate in the synthesis of kinase inhibitors, particularly for targeted cancer therapies. Its structure supports binding to ATP sites in kinases, making it valuable in developing drugs for oncology research. Also employed in the design of covalent inhibitors due to the presence of the methacrylamide group, which can react selectively with cysteine residues in proteins. Additionally, this compound serves as a building block in the preparation of fluorescent probes for biochemical assays and cellular imaging, leveraging the pyrrolopyrimidine core’s photophysical properties.
