HPLC of Formula: 14248-66-9. Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms. Compound: 3,5-Dimethyl-4-nitropyridine 1-oxide, is researched, Molecular C7H8N2O3, CAS is 14248-66-9, about The influence of steric effect on 1H NMR, 13C NMR, and IR spectra of methylated derivatives of 4-nitropyridine N-oxide. Author is Puszko, A.; Wasylina, L..
The 1H NMR, 13C NMR, and IR spectra of 2-methyl-. 2,3-dimethyl-, 2,5-dimethyl-, 2,6-dimethyl-, 3,5-dimethyl-, and 2,3,6-trimethyl-4-nitropyridine N-oxides were interpreted. The influence of electron properties of substituents on changes of chem. shifts was analyzed. It was found that “”ortho-effect”” of the Me group inhibits paramagnetism of the nitro group. The ratio between a given substituted heterocyclic compound, its parent compound and the identically substituted benzene derivatives has been determined It was found that the effect of the nitro group on chem. shift and the so-called back donation is modified by electronegativity and the position of the substituent.
From this literature《The influence of steric effect on 1H NMR, 13C NMR, and IR spectra of methylated derivatives of 4-nitropyridine N-oxide》,we know some information about this compound(14248-66-9)HPLC of Formula: 14248-66-9, but this is not all information, there are many literatures related to this compound(14248-66-9).
