Medchemexpress LLC Permethrin-d5 | 1794760-19-2 | 99.2% | 1 MG
Permethrin-d5 (NRDC-143-d5) is the deuterium labeled Permethrin. Permethrin (NRDC-143) is an insecticide, acaricide, and insect repellent; it functions as a neurotoxin by affecting neuron membranes and prolonging sodium channel activation. It is for research use only.
- Can be used as a tracer.
- Can be used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS.
- Stable heavy isotopes are incorporated into drug molecules for quantitation during the drug development process.
- Deuteration can affect the pharmacokinetic and metabolic profiles of drugs.
