Abstract

Provided are 3-nitro-1,2,4-triazole-5-one-d2 and a preparation method and use thereof. Compared with 3-nitro-1,2,4-triazole-5-one, the 3-nitro-1,2,4-triazole-5-one-d2 provided by the disclosure has an increased molecular relative molar mass, which leads to the increase in crystal density. By substituting hydrogen atoms with deuterium atoms, it is possible to avoid the influence of hydrogen atoms on neutron diffraction signal-to-noise ratio. Compared with carbon-hydrogen bond, carbon-deuterium bond has lower zero point energy, lower vibration frequency and more stability, allowing 3-nitro-1,2,4-triazole-5-one-d2 to have high density, excellent detonation performance, high detonation velocity, high stability, low thermal sensitivity, low friction sensitivity and low impact sensitivity.
