3,5-Dinitro-1-(3,3,3-trifluoropropyl)-1H-pyrazol-4-amine as an insensitive and thermostable energetic melt-castable material†

A trifluoropropyl functionalized energetic compound, viz. 3,5-dinitro-1-(3,3,3-trifluoropropyl)-1H-pyrazol-4-amine (TFDNPA), was designed and synthesized, which exhibited potential for TNT replacement as an energetic melt-castable carrier in aluminized explosive formulation due to excellent thermal properties (T_m: 100 °C and T_d: 261 °C), good detonation performance (D: 7330 m s⁻¹ and P: 23.3 GPa), low impact sensitivity (IS: 35 J) and enhanced reaction activity with aluminium powders in melt-cast explosive formulations.
