Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and antiviral agents. Its structure supports the design of bioactive molecules by enhancing metabolic stability and binding affinity. Commonly employed in medicinal chemistry for constructing pyrimidine-based drug candidates. Also utilized in agrochemicals for the development of herbicides and pesticides due to its electron-withdrawing properties and ability to improve compound persistence in environmental conditions.
