Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of herbicides and fungicides. It serves as a building block in agrochemical manufacturing due to its reactive chlorine and methoxy groups, which allow for easy functionalization. Commonly employed in cross-coupling reactions to form more complex pyrimidine derivatives with biological activity. Also utilized in the production of certain kinase inhibitors and other bioactive molecules in medicinal chemistry research, including treatments for viral infections, cancer, and neurological disorders.
