Medchemexpress LLC Heptadecanoic acid-d33 | 352431-41-5 | 303.65 | 5 MG
Heptadecanoic acid-d33 is the deuterium labeled Heptadecanoic acid. Heptadecanoic acid is an odd chain saturated fatty acid (OCS-FA) associated with several diseases, including coronary heart disease, prediabetes, type 2 diabetes, and multiple sclerosis. 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.
- Can be used as a tracer
- Can be used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS
