Isotopically Labeled Compounds
Medchemexpress LLC Squalane-d62 | 16514-83-3 | 25 MG
Squalane-d62 is a deuterium-labeled form of Squalane, a saturated derivative of Squalene found in certain fish and vegetable oils. It exhibits anticancer, antioxidant, skin hydrating, and emollient activities. This product is intended for research use only. Stable heavy isotopes, such as deuterium, are incorporated into drug molecules primarily as tracers for quantitation during drug development, and can influence the pharmacokinetic and metabolic profiles of drugs.
- Can be used as a tracer.
- Can be used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS.
- Stable under recommended storage conditions.
