Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of herbicides and fungicides. Its electrophilic nature makes it suitable for nucleophilic substitution reactions, enabling the introduction of various functional groups in active ingredient formulations. Commonly employed in the production of crop protection agents due to its ability to enhance the biological activity and stability of the final compounds. Also utilized in research for the development of novel pyrimidine-based bioactive molecules.
