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 constructing complex heterocyclic systems. Commonly employed in agrochemical research for designing novel pesticides due to its reactivity and stability in multi-step reactions. Also utilized in the preparation of functionalized pyrimidine derivatives for use in materials science and as building blocks in combinatorial chemistry.
