Isotopically Labeled Compounds
Medchemexpress LLC Salcaprozate-d4 sodium (SNAC-d4 sodium) | 203787-91-1 | 99.7% | 305.34 | 1 MG
Salcaprozate-d4 (sodium) is a deuterated labeled Salcaprozate (sodium). Salcaprozate sodium (SNAC) is an oral absorption promoter with potential as a delivery agent for oral forms of heparin and insulin. It can increase passive transcellular permeation across small intestinal epithelia by increasing lipophilicity from non-covalent macromolecule complexation.
- Deuterated labeled compound.
- 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 of hydrogen, carbon, and other elements are incorporated into the drug molecule.
- Potential to affect the pharmacokinetic and metabolic profiles of drugs.
Medchemexpress LLC 5-Methylcytosine-d4 | 1219795-15-9 | 129.15 | 5 MG
5-Methylcytosine-d4 is the deuterium labeled version of 5-Methylcytosine. 5-Methylcytosine is a known DNA modification in prokaryotes and eukaryotes. It forms symmetrical methylation on CpG dinucleotides in DNA, stabilizes tRNA/rRNA structure in RNA, and influences mRNA translation. It can be oxidized to produce 5hmC, 5fC, and 5caC. 5-Methylcytosine is used in epigenetics, developmental biology, and research on diseases such as colorectal cancer and hepatocellular carcinoma.
- Can be used as a tracer
- Can be used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS
