Boc-L-Valine-d8 is the deuterium labeled Boc-L-Valine. It can be used as a tracer and as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS. Stable heavy isotopes of hydrogen, carbon, and other elements like this have been incorporated into drug molecules, largely as tracers for quantitation during the drug development process. Deuteration has gained attention due to its potential to affect the pharmacokinetic and metabolic profiles of drugs.
- Used as a tracer
- Used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS
