Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other biologically active compounds. Its halogenated pyrimidine structure allows for selective cross-coupling reactions, making it valuable in medicinal chemistry for building complex drug molecules. Commonly employed in the preparation of antitumor agents and anti-inflammatory drugs due to its ability to modulate biological targets. Also utilized in agrochemical research for designing novel pesticides and herbicides.
