Medchemexpress LLC trans-Zeatin-d5 | 72963-19-0 | 99.2% | 224.27 | 1 MG
trans-Zeatin-d5 is deuterium labeled trans-Zeatin, a plant cytokinin vital for cell growth, differentiation, and division. It also inhibits UV-induced MEK/ERK activation. This compound can serve as a tracer and an internal standard for quantitative analysis using techniques like NMR, GC-MS, or LC-MS. Incorporating stable heavy isotopes into drug molecules primarily assists in quantitation during drug development, and deuteration can influence the pharmacokinetic and metabolic profiles of drugs.
