Medchemexpress LLC Tri-p-tolylamine-d21 | 201944-90-3 | 98.2% | 308.53 | 5 MG
Tri-p-tolylamine-d21 is the deuterium labeled Tri-p-tolylamine. This compound can be used as a tracer and as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS. Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into drug molecules, largely as tracers for quantitation during the drug development process. Deuteration has gained attention because of its potential to affect the 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
Cayman Chemical Gliclazide-d4, Purity: ≥99% deuterated forms (d1-d4), CAS: 1185039-30-8, 5 mg
An internal standard for the quantification of gliclazide by GC- or LC-MS
Medchemexpress LLC L-ornithine-d7 hydrochloride | 2483831-57-6 | 99.9% | 175.67 | C5H6D7ClN2O2 | 5 MG
L-ornithine-d7 hydrochloride is the deuterium-labeled hydrochloride salt of L-ornithine used as an internal standard and reference material for analytical workflows. Supplied as a white to off-white solid, it is intended for quantitative mass spectrometry, metabolomics, and isotope tracing studies where isotopic labeling is required.
