Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antiviral and anticancer agents. Its reactive chloromethyl group allows for easy functionalization, making it valuable in constructing complex pyrimidine-based molecules. Commonly employed in agrochemical research for designing novel pesticides and herbicides due to its ability to enhance bioactivity. Also utilized in materials science for creating specialty polymers and electronic chemicals where halogenated pyrimidines contribute to desired thermal or electronic properties.
