Displaying 9 results of Phenytoin Stable Isotopes Phenytoin Stable Isotopes refer to the non-radioactive versions of the chemical element Phenytoin. These isotopes have a stable nucleus and are commonly used in scientific research, medical diagnostics, and drug development. They are essential in understanding the metabolism, pharmacokinetics, and pharmacodynamics of Phenytoin, a medication used to treat seizures. Phenytoin Stable Isotopes are crucial in the development of new drugs and therapies, allowing for accurate measurements and observations without the risks associated with radioactive isotopes.
