Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of antiviral and anticancer agents. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for building pyrimidine-based drug candidates. Commonly employed in cross-coupling reactions due to the presence of halogen groups, enabling the formation of C–C and C–heteroatom bonds. Also utilized in agrochemical research for designing bioactive molecules with pesticidal or herbicidal activity.
