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, contributing to the creation of herbicides and fungicides due to its reactivity in cross-coupling reactions. Its chloromethyl group allows for easy functionalization, making it valuable in medicinal chemistry for introducing pyrimidine moieties into larger bioactive molecules. Also employed in the preparation of dyes and specialty polymers where halogenated heterocycles enhance material stability and electronic properties.
