Medchemexpress LLC Benzyl Paraben-d7 | 1216916-40-3 | 235.29 | 5 MG
Benzyl Paraben-d7 is a deuterium-labeled Benzyl 4-hydroxybenzoate, which is a prominent material used as an excipient. It can function as a bacteriostatic agent or preservative in pharmaceutical preparations, improving stability, solubility, and processability. Excipients also influence the absorption, distribution, metabolism, and elimination (ADME) processes of co-administered drugs. This product is for research use only and has not been fully validated for medical applications.
- Deuterium-labeled compound
- Can be used as a bacteriostatic agent
- Functions as a preservative
- Improves stability and solubility of pharmaceutical preparations
- Affects ADME processes of co-administered drugs
Medchemexpress LLC 5'-Guanylic acid-15N5 dilithium | 85-32-5 | 5 MG
5'-Guanylic acid-15N5 dilithium is the 15N labeled version of 5'-Guanylic acid. 5'-Guanylic acid (5'-GMP) plays a role in several metabolic disorders, including the AICA-ribosiduria pathway, adenosine deaminase deficiency, adenine phosphoribosyltransferase deficiency (aprt), and the 2-hydroxyglutric aciduria pathway. It is intended for research use only and not for sale to patients.
- Utilized as a tracer.
- Serves as an internal standard for quantitative analysis using techniques such as NMR, GC-MS, or LC-MS.
- Stable heavy isotope.
- Involved in metabolic pathways.
- Intended for research use only.
Medchemexpress LLC POPEth-d5 | 1612140-92-7 | 98.0% | 725.04 | 500 UG
POPEth-d5 is deuterium labeled POPEth. 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.
Medchemexpress LLC Mefenamic Acid-d3 | 1189707-81-0 | 2.5 MG
Mefenamic Acid-d3 is the deuterium labeled Mefenamic acid. Mefenamic acid is a BBB-permeable non-steroidal anti-inflammatory agent, acting as a competitive inhibitor of hCOX-1 and hCOX-2, with IC50s of 40 nM and 3 μM, respectively. It can be used as a tracer or an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS.
- Deuterium labeled mefenamic acid
- BBB-permeable non-steroidal anti-inflammatory agent
- Acts as a competitive inhibitor of hCOX-1 and hCOX-2
- Suitable as a tracer for research
- Functions as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS
