Webdeuterated form, it adds three more signals to the spectrum (methylenes 1, 2, and 3 appear at 2.91, 1.76, and 0.63 ppm, respectively). We suggest that the re-sidual HDO peak be used as a secondary reference; we find that if the effects of temperature are taken into account (vide infra), this is very reproducible. For D 2O, WebDeuterated compounds have a long history of use in humans as metabolic and pharmacokinetic probes. In contrast, there have been few reports of deuterated compounds being studied as potential new drugs. Fludalanine (2-deutero-3-fluoro-D-alanine), developed by Merck, appears to be the most extensively studied deuterated drug candidate.
