Used as a key intermediate in the synthesis of fluorinated pyrimidine derivatives, particularly in pharmaceuticals targeting antiviral and anticancer agents. Its nitrile and fluorine groups enable selective functionalization, making it valuable in medicinal chemistry for building active pharmaceutical ingredients (APIs). Commonly employed in the development of kinase inhibitors and nucleoside analogs due to its ability to mimic natural nucleobases while enhancing metabolic stability and binding affinity. Also utilized in agrochemical research for designing novel pesticides with improved efficacy and selectivity.
