Displaying 3 results of Lumefantrine Stable Isotopes Lumefantrine stable isotopes are non-radioactive versions of the chemical element lumefantrine. These isotopes have the same number of protons and electrons as the naturally occurring lumefantrine, but differ in the number of neutrons. These isotopes are used in research and development to study the pharmacokinetics and metabolism of lumefantrine, as well as to create standards for analytical measurements. The stable isotopes of lumefantrine are safe to handle and do not pose any radiation risks.
