Organic functional group analysis at the micromole level. I. Determination of the N-oxide function by differential pulse polarography was written by Ma, T. S.;Hackman, M. R.;Brooks, M. A.. And the article was included in Mikrochimica Acta in 1975.SDS of cas: 3718-65-8 This article mentions the following:
Pyridine N-oxides (≥0.5 μg/ml) can be determined by differential pulse polarog. in 1.0M phosphate buffer (pH 3.0) in 2.5% MeOH. The peak potentials were -1.100 ± 0.150 V vs. SCE for the reduction of the N-oxide function in pyridine 1-oxide, 2-picoline 1-oxide, 3-picoline 1-oxide, 4-picoline 1-oxide, 2-cyanopyridine 1-oxide, 2-benzylpyridine 1-oxide, 4-chloropyridine 1-oxide, 4-nitropyridine 1-oxide, 3,5-lutidine 1-oxide, and 2,6-dibromopyridine 1-oxide. The calibration curve was linear for ∼3-30 μM 2-benzylpyridine 1-oxide. In the experiment, the researchers used many compounds, for example, 3,5-Dimethylpyridine 1-oxide (cas: 3718-65-8SDS of cas: 3718-65-8).
3,5-Dimethylpyridine 1-oxide (cas: 3718-65-8) belongs to pyridine derivatives. Pyridine is diamagnetic and has a diamagnetic susceptibility of −48.7 × 10−6 cm3·mol−1.The molecular electric dipole moment is 2.2 debyes. The standard enthalpy of formation is 100.2 kJ·mol−1 in the liquid phase and 140.4 kJ·mol−1 in the gas phase. Halopyridines are particularly attractive synthetic building blocks in a variety of cross-coupling methods, including the Suzuki-Miyaura cross-coupling reaction.SDS of cas: 3718-65-8
