Displaying 2 results of Cefdinir Stable Isotopes Cefdinir Stable Isotopes are non-radioactive isotopes of the antibiotic drug cefdinir. These isotopes are used in the development and testing of new drugs, as well as in medical research. They are chemically identical to the naturally occurring isotopes of cefdinir, but have a different number of neutrons in the nucleus. This makes them useful for studying the pharmacokinetics and metabolism of the drug, as well as for tracing its movement through the body. Cefdinir Stable Isotopes are safe to handle and can be used in a variety of laboratory settings.
