Used as a key intermediate in the synthesis of agrochemicals, particularly herbicides and fungicides. Its structure allows for the development of compounds with high selectivity and efficacy against a range of plant pathogens and weeds. It is also employed in the preparation of pharmaceuticals where the pyrimidine core contributes to biological activity, especially in antiviral and anticancer agents. The presence of reactive chlorine and difluoromethyl groups enables further functionalization, making it valuable in medicinal chemistry for structure-activity relationship studies.
