Use	Application of acetic anhydride -13C4 as acetic anhydride isotope marker, with convenient detection, high sensitivity, can be used to study the acetic anhydride metabolism, synthesis or decomposition in vivo; it can also be used in medical experiments as a means of tracking the site of action and metabolism of acetic anhydride. Isotopes are the same element with different masses but the same chemical properties. The method of replacing an atom in a molecule with its isotope is called isotope labeling.
