General description
Application
- Estimation of dissociation constants (pKa′s) of oximes from proton chemical shifts in dimethyl sulfoxide solution: This research utilizes Dimethyl sulfoxide-d₆ (DMSO-d₆) to determine pKa values of oximes, demonstrating its crucial role in enhancing the accuracy of proton NMR spectroscopy for chemical analysis and research within pharmaceutical contexts (Kurtz AP, D′Silva TD, 1987).
- Proton nuclear magnetic resonance studies on methylthiohydantoins, thiohydantoins, and hydantoins of amino acids: DMSO-d₆ is extensively employed to investigate the structure and behavior of various hydantoin derivatives in amino acid research, proving essential for understanding protein structures and functions, with implications for both academic and pharmaceutical industries (Suzuki T, Tomioka T, Tuzimura K, 1977).
