Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in agrochemicals for creating herbicides and pesticides due to its reactive functional groups. Its chloropyrimidine structure allows for easy modification in organic synthesis, making it valuable in medicinal chemistry for constructing more complex molecules. Also employed in research settings for designing new bioactive compounds with potential antiviral or anti-inflammatory properties.
