Cas no 19183-17-6 (1,2-dimethyl-4,5-dinitro-1H-imidazole)

1,2-Dimethyl-4,5-dinitro-1H-imidazole is a high-energy nitroimidazole derivative characterized by its thermally stable and explosive properties. The compound features a rigid imidazole backbone substituted with two nitro groups at the 4,5-positions and methyl groups at the 1,2-positions, enhancing its density and stability. Its balanced molecular structure contributes to predictable detonation performance, making it suitable for specialized energetic applications. The presence of nitro groups provides high oxygen content, improving combustion efficiency, while the methyl substitutions reduce sensitivity to friction and impact compared to analogous nitroimidazoles. This compound is primarily of interest in propellant formulations and pyrotechnic research due to its controlled decomposition behavior and compatibility with other energetic materials.
