Medchemexpress LLC D-Fructose-d7 | 100 MG
D-Fructose-d7 is the deuterium labeled D-Fructose. D-Fructose (D(-)-Fructose) is a naturally occurring monosaccharide found in many plants. For research use only. We do not sell to patients.
- Can be used as a tracer.
- Can be used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS.
- Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into drug molecules, largely as tracers for quantitation during the drug development process.
- Deuteration has gained attention because of its potential to affect the pharmacokinetic and metabolic profiles of drugs.
