Medchemexpress LLC D-Glucose-d4 | 478529-49-6 | 99.0% | 5 MG
D-Glucose-d4 is the deuterium-labeled form of D-Glucose. D-Glucose, a monosaccharide, is a significant carbohydrate in biology, functioning as a carbohydrate sweetener and a crucial component of general metabolism. It also serves as a critical signaling molecule. Stable heavy isotopes of hydrogen, carbon, and other elements, such as deuterium, are incorporated into drug molecules, primarily as tracers for quantitative analysis during drug development. Deuteration is gaining attention due to its potential to influence the pharmacokinetic and metabolic profiles of drugs.
- Utilized as a tracer
- Internal standard for quantitative analysis
- Used in techniques like NMR, GC-MS, or LC-MS
