Isotopically Labeled Compounds
Medchemexpress LLC Gallic acid-d2 (3,4,5-Trihydroxybenzoic acid-d2) | 294660-92-7 | 172.13 | 5 MG
Gallic acid-d2 is the deuterium labeled Gallic acid. Gallic acid (3,4,5-Trihydroxybenzoic acid) is a natural polyhydroxyphenolic compound and a free radical scavenger that inhibits cyclooxygenase-2 (COX-2). Gallic acid exhibits various activities, including antimicrobial, antioxidant, anti-inflammatory, and anticancer activities.
- Can be used as a tracer and as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS.
- Deuteration has the potential to affect the pharmacokinetic and metabolic profiles of drugs.

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.
