Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in medicinal chemistry due to its ability to undergo further functionalization on the pyrimidine ring. Commonly employed in the preparation of biologically active molecules, including antiviral and anticancer agents. Its ester group allows for easy modification or coupling in multi-step organic syntheses. Also utilized in agrochemical research for designing novel active ingredients.
