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. It is also employed in agrochemical research for designing novel pesticides and herbicides due to its reactivity and ability to form stable derivatives. Commonly utilized in cross-coupling reactions, such as Suzuki and Stille reactions, to introduce aryl or heteroaryl groups during the construction of complex molecules.
