Levamisole-d5 Hydrochloride is a stable isotope-labeled molecule that is a derivative of levamisole. This modification enhances its utility in scientific research, especially in the fields of analytical chemistry. The incorporation of deuterium into the levamisole molecule makes levamisole-d5 hydrochloride an invaluable tool for mass spectrometry (MS) and nuclear magnetic resonance (NMR) spectroscopy. In mass spectrometry, the deuterium labeling allows for the precise and accurate quantification of levamisole through the differentiation between the labeled and unlabeled molecules, which is critical in the analysis of complex biological matrices. This is particularly useful in pharmacokinetic studies, where understanding the absorption, distribution, metabolism, and excretion (ADME) of substances is essential.
