Recommanded Product: 6-Hydroxy-2-methylpyrimidin-4(3H)-one. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: 6-Hydroxy-2-methylpyrimidin-4(3H)-one, is researched, Molecular C5H6N2O2, CAS is 1194-22-5, about Investigation of FOX-7 Polymorphs: new polymorphs – ε and ζ. Author is Kushtaev, Alexander A.; Yudin, Nikolay V.; Kondakova, Natalia N.; Ilicheva, Natalia N.; Vu, Tuan Q.; Zbarskiy, Vitold L..

Polymorphism of 1,1-diamino-2,2-dinitroethene (FOX-7, DADNE) has investigated by X-ray powder diffraction (XRD), differential scanning calorimetry (DSC), thermo gravimetric anal. (TGA), IR-spectroscopy. Two previously unknown polymorph modifications of FOX-7 – ε and ζ were discovered. ε-FOX-7 has prepared by hydrolysis of 2-(dinitromethylene)-5,5-dinitropyrimidine-4,6(1H,3H,5H)-dione in a media with pH up 7-8 to Ho≈-3 and 2-(dinitromethylene)imidazolidine-4,5-dione in aqueous ammonia. Ε-FOX-7 is a stable and exists in temperature range 273-378 K. ζ-polymorph of FOX-7 can be obtained at ε-FOX-7 heating to 378-380 K. ζ→ε polymorph transition is a reversible and occurs at 361.7±3.1 K. At 433-453 K ζ-FOX-7 transforms to γ-polymorph. ζ→γ phase transition temperature range was determined using IR-spectroscopy because it is invisible on DSC curves. IR-spectra of ε and ζ polymorphs are significantly distinct from α-, β- and γ-FOX-7. ε-FOX-7, in contrast to monoclinic α-polymorph, has orthorhombic type of crystal system (space group P212121). Based on received data, new scheme of FOX-7 polymorph transition is proposed.

In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Energetic Salts with π-Stacking and Hydrogen-Bonding Interactions Lead the Way to Future Energetic Materials, published in 2015-02-04, which mentions a compound: 1194-22-5, Name is 6-Hydroxy-2-methylpyrimidin-4(3H)-one, Molecular C5H6N2O2, Application of 1194-22-5.

Among energetic materials, there are two significant challenges facing researchers: (1) to develop ionic CHNO explosives with higher densities than their parent nonionic mols. and (2) to achieve a fine balance between high detonation performance and low sensitivity. We report a surprising energetic salt, hydroxylammonium 3-dinitromethanide-1,2,4-triazolone, that exhibits exceptional properties, viz., higher d., superior detonation performance, and improved thermal, impact, and friction stabilities, then those of its precursor, 3-dinitromethyl-1,2,4-triazolone. The solid-state structure features of the new energetic salt were investigated with X-ray diffraction which showed π-stacking and hydrogen-bonding interactions that contribute to closer packing and higher d. According to the exptl. results and theor. anal., the newly designed energetic salt also gives rise to a workable compromise in high detonation properties and desirable stabilities. These findings will enhance the future prospects for rational energetic materials design and commence a new chapter in this field.

Computed Properties of C5H7NO3, Chemical research careers are more diverse than they might first appear, as there are many different reasons to conduct research and many possible environments.

The synthesis of 3-(dimethylamino)-2,2-dimethyl(1-15N)-2H-azirine (1*) was accomplished via reaction of 1-chloro-N,N,2-trimethyl-1-propenylamine (9) and sodium (1-15N) azide (Scheme 3).The earlier reported reactions of 1 with saccharin (10, Scheme 4), phthalimide (12, Scheme 5), and 2H-1,3-benzoxazin-2,4(3H)-dione (16, Scheme 6) were repeated with 1*, and the position of the 15N-label in the products was determined by 15N-NMR spectroscopy.Whereas the postulated reaction mechanismus for 10 and 12 were confirmed by those experiments, the mechanism for the reaction of 16 had to be revised.With respect to the position of 15N in the products 17 and 18, a new mechanism is formulated in Scheme 7.Treatment of 5,5-dimethyl-1,3-oxazolidine-2,4-dione (19) with 1* led to 3,4-dihydro-2H-imidazol-2-on 20 in which only N(3) was labelled.The mechanism of a ring expansion and transannular ring contraction as shown in Scheme 8 is in agreement with this finding.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Computed Properties of C5H7NO3, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 695-53-4, in my other articles.
