Displaying 8 results of Emtricitabine Stable Isotopes Emtricitabine Stable Isotopes are isotopically labeled forms of Emtricitabine, a nucleoside reverse transcriptase inhibitor used in the treatment of HIV infection. These stable isotopes have the same chemical and physical properties as the non-labeled compound but with different masses, making them useful in studies of drug metabolism, pharmacokinetics, and drug interactions. They are also used in the development and validation of analytical methods for the quantification of Emtricitabine in biological matrices.
