Reaching the goal of developing an insensitive high-energy molecule () is a major challenge. In this study, 3,5-diamino-6-hydroxy-2-oxide-4-nitropyrimidone () was synthesized in one step from 2,4,6-triamino-5-nitropyrimidine-1,3-dioxide hydrate (ICM-102 hydrate). The density of compound is 1.95 g cm with a decomposition temperature of 271 °C. Its detonation velocity and pressure are 8660 m s and 33.64 GPa, respectively, which are far superior to the detonation performance of 1,3,5-triamino-2,4,6-trinitrobenzene (TATB), while its sensitivity is identical with that of TATB. In addition, four derivatives (, chloride; , nitrate; , perchlorate; and , dinitramide) were prepared on the basis of the weak base site (N-O group) and show excellent energetic properties. By combining a series of advantages, including simple preparation, high yield, high density, very low solubility in aqueous solution, high thermostability, insensitivity, and excellent detonation performance, approaches an ideal insensitive high-energy molecule. Compounds - are also competitive as new high-energy-density materials.
