Displaying 1 results of Tulathromycin A Stable Isotopes Tulathromycin A Stable Isotopes are a set of isotopically labeled compounds used in analytical chemistry and pharmacology. They are used as internal standards for quantitative analysis of tulathromycin, a macrolide antibiotic commonly used in veterinary medicine. These stable isotopes are chemically identical to the non-labeled form of tulathromycin A, but contain a specific number of stable isotopes, making them useful in precision measurements and drug metabolism studies.
