Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of antibiotics such as trimethoprim (often used in combination with sulfonamides) and antiviral agents. It serves as a building block in the development of pyrimidine-based drugs, which are important in treating various infections and inflammatory conditions. Also employed in research for the design of novel heterocyclic compounds with potential biological activity. Its structure allows for easy functionalization, making it valuable in medicinal chemistry for creating compound libraries in drug discovery. Additionally, it finds applications in the synthesis of functional materials, including luminescent compounds and organic electronics requiring specific optical or conductive properties.
