Medchemexpress LLC Arachidic acid-d39 | 39756-32-6 | 351.77 | 10 MG
Arachidic acid-d39 is the deuterium labeled Arachidic acid (HY-W004260), also known as Eicosanoic acid. It is a long-chain saturated fatty acid found in plasma phospholipid, fish, cannabis, and other plant oils. This compound can be used for anti-cancer drug delivery research when conjugated with Chitosan oligosaccharide.
- Used as a tracer.
- Used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS.
- Stable heavy isotopes are incorporated into drug molecules as tracers for quantitation.
- Deuteration affects pharmacokinetic and metabolic profiles of drugs.
