Reference of 1837-55-4, 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. 1837-55-4, Name is 3,5-Dichloropyridazine, molecular formula is C4H2Cl2N2. In a Article，once mentioned of 1837-55-4

The synthesis of 3,5-diamino-4,6-dinitropyridazine-1-oxide (8) is reported. It is prepared in a six-step synthetic procedure starting from acyclic compounds, and shows good properties (detonation velocity DC?J = 8486 m s?1, detonation pressure pC?J = 302 kbar), and sensitivity toward mechanical stimuli. Compound 8 and its precursor (7, 3,5-dimethoxy-4,6-dinitropyridazine-1-oxide) were characterized by means of multinuclear (1H, 13C, 14N, 15N) NMR spectroscopy, mass spectrometry, vibrational spectroscopy (IR and Raman), elemental analysis and differential thermal analysis (DTA) measurements. Compounds 4, 5, 6, 7, 8 and 9 were also characterized by low-temperature single-crystal X-ray diffraction. The heats of formation for 7 and 8 were calculated using the atomization method based on CBS-4M enthalpies. Using the experimentally determined (X-ray) densities and the calculated standard molar enthalpies of formation, several detonation parameters such as the detonation pressure, energy and velocity were predicted by using the EXPLO5 code (V6.03). The sensitivities of 3,5-dimethoxy-4,6-dinitropyridazine-1-oxide (7) and 3,5-diamino-4,6-dinitropyridazine-1-oxide (8) toward impact, friction and electrical discharge were tested according to BAM standards. In addition, the shock reactivity of 8 was measured by applying the small-scale shock reactivity test, showing similar values to HNS, PYX and TKX-55.

Electric Literature of 1837-55-4, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 1837-55-4, 3,5-Dichloropyridazine, introducing its new discovery.

In the present studies, the synthesis of new energetic materials based on the pyridazine scaffold and their characterization is the main subject. For this purpose, desired 3,5-dimethoxy-4,6-dinitropyridazine-1-oxide (7) was synthesized in the first instance. The persubstituted pyridazine precursor laid the groundwork for further preparative modification. The targeted functionalization through the regioselective introduction of various smaller amine nucleophiles such as methylamine or 2-aminoethanol gave several new energetic materials. Among them are 3,5-bis(methylamino)-4,6-dinitropyridazine-1-oxide (8), 3,5-bis(methylnitramino)-4,6-dinitropyridazine-1-oxide (9), 3,5-bis(dimethylamino)-4,6-dinitropyridazine-1-oxide (10), and 3,5-bis((2-hydroxyethyl)amino)-4,6-dinitropyridazine-1-oxide (11). With the aim of increasing the detonation performance, compound 8 was additionally nitrated and 3,5-bis(methylnitramino)-4,6-dinitropyridazine-1-oxide (9) was obtained. These new energetic materials were characterized and identified by multinuclear NMR (1H, 13C, 14N, 15N) and IR spectroscopy, elemental analysis and mass spectrometry. In addition, their sensitivities toward impact, friction and electrostatic discharge were thoroughly examined. Furthermore, obtained single-crystals of the substances were characterized by low-temperature single-crystal X-ray diffraction.
