Ondansetron-d5（Cat No.:S000324） is a deuterated form of ondansetron, where five hydrogen atoms are replaced with deuterium, enhancing its molecular stability and making it useful as an analytical standard, especially in mass spectrometry and NMR spectroscopy. Ondansetron itself is a widely used antiemetic medication that prevents nausea and vomiting associated with chemotherapy, radiation therapy, and post-surgery. The incorporation of deuterium in ondansetron-d5 facilitates more precise studies of the drug’s pharmacokinetics and metabolism, helping researchers understand its absorption, distribution, metabolism, and excretion processes in greater detail.
