Medchemexpress LLC 2-Furoic acid-d3 | 40073-83-4 | 99.99% | 115.10 | 100 MG
2-Furoic acid-d3 is the deuterium labeled 2-Furoic acid. 2-Furoic acid (Furan-2-carboxylic acid) is an organic compound produced through furfural oxidation. 2-Furoic acid exhibits a hypolipidemic effect, lowering both serum cholesterol and serum triglyceride levels in rats. 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
