Displaying 6 results of Pemetrexed Stable Isotopes Pemetrexed stable isotopes are a set of isotopes that are used in the development of Pemetrexed, a chemotherapeutic drug used in the treatment of various types of cancer. These isotopes are classified as stable, meaning they do not undergo radioactive decay and are therefore safe to handle. They are commonly used in research and development studies to help identify and isolate the active ingredients in Pemetrexed, as well as to ensure its purity and stability. Additionally, these stable isotopes can also be used in clinical trials to help improve the efficacy and safety of Pemetrexed for cancer patients.
