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 Dipole moments and spectroscopic properties of methyl-4-nitropyridine N-oxides, published in 1996-07-31, which mentions a compound: 14248-66-9, Name is 3,5-Dimethyl-4-nitropyridine 1-oxide, Molecular C7H8N2O3, HPLC of Formula: 14248-66-9.
Mol. dipole moments and dipole moments of interaction of 7 Me derivatives of 4-nitropyridine N-oxides were determined in benzene solution Polar and 13C-NMR and UV/Vis manifestations of intramol. interaction indicate that the Me groups modify the electronic interaction between the NO and NO2 groups mainly through steric strain.
This literature about this compound(14248-66-9)HPLC of Formula: 14248-66-9has given us a lot of inspiration, and I hope that the research on this compound(3,5-Dimethyl-4-nitropyridine 1-oxide) can be further advanced. Maybe we can get more compounds in a similar way.
