Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of antifungal and antiviral drugs. Its structure supports the creation of bioactive molecules by serving as a building block in heterocyclic chemistry. Commonly employed in medicinal chemistry for modifying pyrimidine-based compounds to enhance metabolic stability and binding affinity. Also utilized in agrochemical research for designing new crop protection agents due to its electron-withdrawing properties and ability to improve compound lipophilicity.
