Isotopically Labeled Compounds
Medchemexpress LLC Pirenzepine-d8 dihydrochloride | 2982740-97-4 | 432.37 | 1 MG
Pirenzepine-d8 dihydrochloride is a deuterium-labeled version of Pirenzepine dihydrochloride. It acts as a selective M1 mAChR (muscarinic acetylcholine receptor) antagonist, reducing gastric acid secretion and muscle spasms. This makes it useful in peptic ulcer research and it also shows anti-proliferative activity against cancer cells.
- Deuterium 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 are incorporated for quantitation during drug development.
- Potential to affect pharmacokinetic and metabolic profiles of drugs due to deuteration.
