Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. Its structure allows for selective modification, making it valuable in creating biologically active molecules. Commonly employed in medicinal chemistry for constructing pyrimidine-based drug candidates with antiviral and anticancer properties. Also utilized in agrochemical research for designing novel pesticides due to its electron-deficient aromatic system that enhances binding to target enzymes.
