Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and antiviral agents. Its structure allows for selective functionalization, making it valuable in creating active pharmaceutical ingredients (APIs) with high specificity. Commonly employed in research settings for constructing pyrimidine-based heterocyclic compounds, it plays a role in drug discovery for cancer therapies and central nervous system disorders. Also utilized in agrochemical research for developing novel pesticides and herbicides due to its reactivity and stability in various coupling reactions.
