Medchemexpress LLC L-Serine-13C3 | 201595-68-8 | 108.07 | 50 MG
SDP

L-Serine-13C3 is the 13C-labeled version of L-Serine, a non-essential amino acid critical for cellular proliferation. Stable heavy isotopes, such as those of carbon, are integrated into drug molecules primarily to serve as tracers for quantitation during drug development. This specific labeling aids in understanding pharmacokinetic and metabolic profiles.

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