Medchemexpress LLC Choline-d9 chloride | 61037-86-3 | 99.9% | 50 MG
Choline-d9 (chloride) is the deuterium-labeled form of choline chloride, an organic compound. It functions as a quaternary ammonium salt, an acyl group acceptor, and a choline acetyltransferase substrate. Choline chloride is also utilized as an important feed additive, particularly for chickens, where it promotes growth.
- Used as a tracer.
- Suitable as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS.
- Deuteration can influence the pharmacokinetic and metabolic profiles of pharmaceuticals.
Medchemexpress LLC (2S)-Gemcitabine-13C,15N2 hydrochloride | 1262897-74-4 | 99.6% | C813CH12ClF2N15N2O4 | 1 MG
(2S)-Gemcitabine-13C,15N2 hydrochloride is a 13C and 15N labeled version of (2S)-Gemcitabine hydrochloride. It is intended for research use only. Stable heavy isotopes, such as those incorporated into this drug molecule, are used as tracers for quantitation during drug development, with deuteration specifically noted for its potential impact on pharmacokinetic and metabolic profiles of drugs.
- Can be used as a tracer.
- Can be used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS.
