Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of sulfonamide antibiotics. It serves as a building block for pyrimidine-based compounds that exhibit antimicrobial and antifungal activities. Its structure allows for easy functionalization, making it valuable in medicinal chemistry for designing drug candidates targeting various enzymes and receptors. Also employed in the preparation of agrochemicals and dyes due to its nitrogen-rich heterocyclic framework.
