Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of pyrimidine-based drugs such as antiviral and anticancer agents. Its structure allows for easy functionalization, making it valuable in medicinal chemistry for building active pharmaceutical ingredients (APIs). Commonly employed in heterocyclic compound synthesis to introduce the pyrimidine ring system, which is prevalent in many biologically active molecules. Also utilized in agrochemical research for developing new crop protection agents due to its reactivity and stability in various chemical transformations.
