L-Methionine-13C,d3 is the 13C- and deuterium labeled L-Methionine. L-Methionine is the L-isomer of Methionine, an essential amino acid for human development, functioning as a hepatoprotectant. Stable heavy isotopes, like those in this compound, are incorporated into drug molecules as tracers for quantitation during drug development. Deuteration can impact the pharmacokinetic and metabolic profiles of drugs. This product is for research use only.

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