A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 274693-26-4, Name is 2-(((3aR,4S,6R,6aS)-6-(7-(((1R,2S)-2-(3,4-Difluorophenyl)cyclopropyl)amino)-5-(propylthio)-3H-[1,2,3]triazolo[4,5-d]pyrimidin-3-yl)-2,2-dimethyltetrahydro-3aH-cyclopenta[d][1,3]dioxol-4-yl)oxy)ethanol, molecular formula is C26H32F2N6O4S.

A high density and insensitive fused [1,2,3]triazolo-pyrimidine energetic material
A novel fused triazolo-pyrimidine energetic compound was synthesized by the two-step diazotization-nitrification method or one-step direct nitration reaction. The physical properties and detonation properties of intermediate 3H-[1,2,3]triazolo[4,5-d]pyrimidine-5,7-diamine (2) and N-(7-oxo-6,7-dihydro-2H-[1,2,3]triazolo[4,5d]pyrimidin-5-yl)nitramide (3) were further explored. Compound 2 has a higher decomposition temperature (368 degrees C) than that of 2,4,6-trinitrotoluene (TNT, 295 degrees C). X-ray crystal-structure analysis shows that the density of compound 3 was 1.97 g cm(-3) at 100 K. Not only the detonation performance of compound 3 (8845 m s(-1), 32.54 GPa) was predicted to approach RDX (8795 m s(-1), 34.9 GPa) but displays significantly good safety properties (36 J), which means that compound 3 may serve as a potential high energy insensitivity material (HEIM).
