A scalable synthesis of 5-(trinitromethyl)-2,4-dihydro-3-1,2,4-triazol-3-one () is possible from commercially available 2-methylpyrimidine-4,6-diol. It exhibits high density (1.90 g cm) with comparably low thermal stability ( = 80 °C) and positive oxygen balance (OB = 20.51%, OB = 0.0%). has an attractive combination of detonation properties ( = 35.01 GPa, = 8997 ms) and propulsive properties ( = 251.85 s, = 478.52 gs cm, ). These are superior to ammonium dinitroamide (ADN), 2,2,2-tetranitroacetimidic acid (TNAA) and ammonium perchlorate (AP), making it a potential green oxidizer in solid rocket propulsion.
由市售的2-甲基嘧啶-4,6-二醇可实现5-(三硝基甲基)-2,4-二氢-3H-1,2,4-三唑-3-酮（）的可扩展合成。它具有高密度（1.90 g/cm³），热稳定性相对较低（Td = 80 °C）且氧平衡为正（OB = 20.51%，OBv = 0.0%）。具有吸引人的爆轰性能（D = 35.01 GPa，v = 8997 m/s）和推进性能（Isp = 251.85 s，ρsp = 478.52 g·s/cm²，）的组合。这些性能优于二硝酰胺铵（ADN）、2,2,2-三硝基乙亚胺酸（TNAA）和高氯酸铵（AP），使其成为固体火箭推进中潜在的绿色氧化剂。
