Displaying 2 results of Diethylcarbamazine Stable Isotopes Diethylcarbamazine (DEC) stable isotopes are a set of isotopes with an unchanging number of protons and neutrons in the nucleus of DEC. These isotopes are used for research purposes in the study of pharmacokinetics, drug metabolism, and drug interactions. They are used as internal standards for mass spectrometric analysis and can be used to trace the fate of DEC in the body. DEC stable isotopes are highly purified and provide accurate and reliable results for scientific studies.
