Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antiviral and anticancer agents. Its structure allows for easy functionalization, making it valuable in medicinal chemistry for building bioactive molecules. Commonly employed in cross-coupling reactions and heterocyclic transformations to introduce the pyrimidine core into drug candidates. Also utilized in agrochemical research for designing novel pesticides with improved metabolic stability due to the presence of the trifluoromethyl group.
