Displaying 7 results of Valproic Acid Stable Isotopes Valproic Acid Stable Isotopes are isotopes of the drug Valproic Acid that have a stable atomic nucleus, meaning they do not undergo radioactive decay. They are used in medical research to study the metabolism and pharmacokinetics of Valproic Acid, as well as in the development of new drugs for the treatment of epilepsy and bipolar disorder. These stable isotopes can be used as internal standards in mass spectrometry analysis, allowing for accurate measurement of drug levels in biological samples.
