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 constructing pyrimidine-based drug candidates. Commonly employed in kinase inhibitor research due to its ability to bind ATP sites in enzymes. Also utilized in agrochemicals for the development of herbicides and pesticides, leveraging its reactivity in cross-coupling reactions. Frequently applied in medicinal chemistry for building blocks in heterocyclic compound libraries.
