Displaying 2 results of Lactide Stable Isotopes Lactide is a cyclic molecule that is used as a precursor for the synthesis of biodegradable polymers such as polylactic acid (PLA). Stable isotopes of lactide, such as carbon-13 and deuterium, are important tools for studying the fate and behavior of these polymers in biological systems. These isotopes can be used to track the breakdown and degradation of PLA in the environment, as well as to monitor its uptake and metabolism in living organisms. Lactide stable isotopes are also used in the synthesis of labeled biomolecules for use in medical research and diagnostics.
