Format. Despite the complexity of the spectrum, propranolol can be viewed as containing 3 spin systems: a fused-ring aromatic (C10H7O), an aliphatic chain (-CHn-) and an isopropyl (i-Pr) group. This site uses cookies. The solvent, DMSO, produces a strong resonance at 2.50 ppm, which is used as a chemical shift reference. The multiplicity of remaining ring protons, C3,4,7,8, appearing between 7.25-7.6 ppm, is obscured by signal overlap, making individual assignment difficult. Only the downfield 13C satellite signal (3.33 ppm; 0.55% intensity) overlaps analyte signals. The triplet at 77 ppm is from the solvent (CDCl 3) carbons split by deuterium (deuterium has a spin quantum number of 1, so it has three spin states). Chemical name: (±) -Propranolol hydrochloride; (±) -1-Isopropylamino-3- (1-naphthyloxy) -2-propanol hydrochloride Concentration: 11.2% (w / w; 0.42 M) in DMSO CAS: 318-98-9 Field: 82 MHz Nuclear testing: 1H Applications: Pharmaceuticals, R & D, Bench Analysis.
