Displaying 7 results of Cefadroxil Stable Isotopes Cefadroxil stable isotopes are non-radioactive forms of the popular antibiotic cefadroxil. These isotopes have the same chemical and physical properties as the natural form of cefadroxil, but with a different number of neutrons in the nucleus. They are used in research and development to study drug metabolism, pharmacokinetics, and drug interactions. Cefadroxil stable isotopes are also used in clinical trials to assess the safety and efficacy of new cefadroxil-based drugs.
