Medchemexpress LLC Artemether-d3 | 93787-85-0 | 301.39 | 1 MG
Artemether-d3 is a deuterium-labeled version of Artemether, an antimalarial drug used to treat resistant strains of falciparum malaria. Deuteration, the incorporation of stable heavy isotopes of hydrogen, carbon, and other elements into drug molecules, is largely used as tracers for quantitation during drug development and has the potential to influence the pharmacokinetic and metabolic profiles of drugs.
- Application as a tracer.
- Internal standard for quantitative analysis.
- High purity.
- Stable isotope.
Cayman Chemical TryptamIn-d4hydrochlorIde 1mg
An internal standard for the quantification of tryptamine by GC- or LC-MS
Alkali Scientific L Ornithine HCl (L 2 5 Diaminopentanoic Acid), 1 Kilogram
L-Ornithine HCl is a key amino acid used in metabolic studies, particularly in the context of urea cycle research and nitric oxide synthesis. Available in a 1-kilogram bottle, it plays a critical role in the biosynthesis of arginine, which is essential for protein synthesis, cell division, and the production of polyamines. L-Ornithine is used as a supplement in cell culture media to promote cell growth and is often employed in animal studies related to liver function, muscle metabolism, and wound healing. It is also used in the synthesis of compounds involved in the regulation of cell growth and differentiation.
