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 13C Satellite-Free 1H NMR Spectra, published in 2017-11-21, which mentions a compound: 73590-85-9, Name is 5-Methoxy-2-[[(4-methoxy-3,5-dimethyl-2-pyridyl)methyl]thio]benzimidazole, Molecular C17H19N3O2S, SDS of 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.
Although many compounds look similar to this compound(73590-85-9)SDS of cas: 73590-85-9, numerous studies have shown that this compound(SMILES:CC1=CN=C(CSC2=NC3=CC(OC)=CC=C3N2)C(C)=C1OC), has unique advantages. If you want to know more about similar compounds, you can read my other articles.
