SDP

Normetanephrine-d3 (hydrochloride) is the deuterium labeled Normetanephrine hydrochloride. Normetanephrine ((±)-Normetanephrine) hydrochloride is the O-methylated metabolite of norepinephrine (NE). It is used for research purposes only and is not sold to patients. Stable heavy isotopes, like deuterium, are incorporated into drug molecules as tracers for quantitation during drug development, with deuteration potentially affecting the pharmacokinetic and metabolic profiles of drugs.

  • Deuterium labeled compound
  • Can be used as a tracer
  • Can be used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS
