Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and antiviral agents. It serves as a building block in agrochemicals for creating herbicides and pesticides due to its reactive nitrile and chlorine functional groups. Its pyrimidine core allows for easy modification in medicinal chemistry, enabling the creation of compounds with enhanced biological activity. Commonly employed in research settings for designing new bioactive molecules and in combinatorial chemistry for drug discovery.
