Displaying 1 results of Gemifloxacin Stable Isotopes Gemifloxacin Stable Isotopes are non-radioactive forms of the antibiotic gemifloxacin. These isotopes have the same chemical and physical properties as the naturally occurring gemifloxacin, but differ in the number of neutrons in their atomic nuclei. They are used in research and development of new drugs to aid in pharmacokinetics and pharmacodynamics studies. The stable isotopes are also used as internal standards in mass spectrometry for accurate quantification of gemifloxacin in biological samples.
