Isotopically Labeled Compounds
Medchemexpress LLC L-Tyrosine-d2-2 | 57746-15-3 | 183.20 | 5 MG
L-Tyrosine-d2-2 is the deuterium labeled L-Tyrosine. L-Tyrosine is a non-essential amino acid which can inhibit citrate synthase activity in the posterior cortex. 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.
