Oseltamivir-d3（Cat No.:S000290） is a deuterated form of oseltamivir, where three hydrogen atoms are replaced with deuterium, improving its molecular stability. This modification makes it especially useful as an internal standard for analytical methods such as mass spectrometry and NMR spectroscopy. Oseltamivir, marketed under the brand name Tamiflu, is an antiviral medication used to treat and prevent influenza A and B. The introduction of deuterium in oseltamivir-d3 enables more accurate and detailed pharmacokinetic and metabolic studies, helping researchers understand the drug’s absorption, distribution, metabolism, and excretion more thoroughly.
