So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Moutzouri, Pinelopi; Kiraly, Peter; Phillips, Andrew R.; Coombes, Steven R.; Nilsson, Mathias; Morris, Gareth A. researched the compound: 5-Methoxy-2-[[(4-methoxy-3,5-dimethyl-2-pyridyl)methyl]thio]benzimidazole( cas:73590-85-9 ).Electric Literature of C17H19N3O2S.They published the article 《13C Satellite-Free 1H NMR Spectra》 about this compound( cas:73590-85-9 ) in Analytical Chemistry (Washington, DC, United States). Keywords: DISPEL NMR one bond satellite signal suppression. We’ll tell you more about this compound (cas:73590-85-9).
A new NMR experiment (Destruction of Interfering Satellites by Perfect Echo Low-pass filtration, DISPEL) is introduced that facilitates the anal. of low-level components in high dynamic range mixtures by suppressing one-bond 13C satellite signals in 1H spectra. Since the natural abundance of 13C is around 1.1%, these satellites appear at 0.54% of the intensity of a parent peak, mimicking and often masking impurity signals. The new experiment suppresses one-bond 13C satellite signals, with high efficiency, at negligible cost in signal-to-noise ratio, and over a wide range of one-bond coupling constants, without the need for broadband 13C decoupling.
Compounds in my other articles are similar to this one(5-Methoxy-2-[[(4-methoxy-3,5-dimethyl-2-pyridyl)methyl]thio]benzimidazole)Electric Literature of C17H19N3O2S, you can compare them to see their pros and cons in some ways,such as convenient, effective and so on.
