WebMar 22, 2024 · The NMR data ( 1 H NMR, and 13 C NMR) of the synthetic sample are in good accordance with the authentic sample from industry [ 28 ]. Overall, this 4-step process (from commercially available aryl idodide substrate 1F) represents the shortest synthesis of eptazocine to date, to the best of our knowledge [ 13, 29 ]. Web• use 13C-NMR spectra to differentiate between the C=O group in a ketone/aldehyde and one in a carboxylic acid derivative; • use IR spectra to identify different C=O groups in an organic molecule.

The chemical shift of the resonance at δ H 10.02 is significantly shifted downfield, and hence, is in the chemical shift range for a carboxylic acid’s hydroxyl proton.. The three proton environments that are left are not resolved appropriately, and hence, it is tough to ascertain their multiplicity and … petguys reviews
