SDP

Tristearin-d5 is the deuterium labeled Tristearin, a triglyceride derived from three units of stearic acid. Stable heavy isotopes of hydrogen, carbon, and other elements are incorporated into drug molecules, primarily as tracers for quantitation during the drug development process. Deuteration can affect the pharmacokinetic and metabolic profiles of drugs.

  • Used as a tracer
  • Used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS
