13/11/2022· It has been demonstrated earlier [2], [12], [39] that methane activation on Cu-loaded ZSM-5 zeolite leads to the formation of three different types of methoxy-like surface intermediates, which are characterized by the following 13 C NMR chemical shifts: 58 ppm for Si–O(CH 3)–Al species, 53 ppm for methanol adsorbed on zeolite BAS, and 63 ppm for Cu–O(CH 3)–Cu or …

Conformation of Roxatidine Acetate Hydrochloride by 1H, 13C and 15N NMR …

Roxatidine acetate hydrochloride is a widely prescribed H2-receptor antagonist for peptic ulcers. Its conformation has been studied using 1H, 13C, and 15N NMR spectroscopy in DMSO-d6 and H2O:D2O (90:10) solvents coupled with AM1 calculations. The results show a folded conformation in DMSO-d6 as opposed to an extended structure in water. Its conformation in DMSO has …

By summing up the building blocks and taking into consideration the functionality suggested by the molecular formula and chemical shifts, it is inferred that Compound 1 is ethyl acetate. 1H NMR (42.5 MHz, neat) δ 3.45 (q, J = 7.1, 2 H, H-1), 1.36 (s, 3 H, H-2’), 0.60 (t, J = 7.1, 3 H, H-2). Figure 4. Compound 1 is ethyl acetate


Chemical Environments The nuer of chemical environment a molecule has is the nuer of peaks in the 13C NMR spectrum.For example: IR has told you that you have an alcohol functional group, but you don’t know if the alcohol is propan-1-ol or propan-2-ol. The 13C NMR will allow you to tell the difference.
