Medchemexpress LLC 3-Hydroxychrysene-d11 | 2468771-62-0 | C18HD11O | 1 MG
3-Hydroxychrysene-d11 is the deuterium labeled 3-Hydroxychrysene. It can be used as a tracer and as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS. The incorporation of stable heavy isotopes of hydrogen, carbon, and other elements into drug molecules serves as tracers for quantitation during drug development. Deuteration, in particular, has garnered attention for its potential to affect the pharmacokinetic and metabolic profiles of drugs.
