Displaying 3 results of Entacapone Stable Isotopes Entacapone stable isotopes refer to the non-radioactive forms of entacapone, a medication used in the treatment of Parkinson's disease. These isotopes are chemically identical to the naturally occurring form of entacapone, but differ in the number of neutrons present in the nucleus. These isotopes are commonly used in research studies to track the metabolism and pharmacokinetics of entacapone in the body. They offer a safe and effective way to study the drug without the risks associated with radioactive isotopes.
