Displaying 4 results of Tolcapone Stable Isotopes Tolcapone Stable Isotopes are a set of non-radioactive isotopes of the drug Tolcapone that are used for research purposes. These isotopes have the same chemical properties as the naturally occurring isotopes of the drug but have different atomic masses, making them useful in various applications such as drug metabolism studies or as internal standards in mass spectrometry experiments. These isotopes are generally more stable and safer to use than their radioactive counterparts, making them a valuable tool for scientific research.
