Flecainide-d3 (CAS 127413-31-4)

Flecainide-d3 is a deuterated variant of flecainide, primarily used in analytical chemistry and research applications for isotope labeling experiments. This modification involves the substitution of hydrogen atoms with deuterium, a stable and non-radioactive isotope of hydrogen, which adds distinctive nuclear properties. By incorporating deuterium, researchers can explore the metabolic pathways and mechanism of action of flecainide with improved accuracy and specificity. The presence of deuterium changes the physical and chemical properties slightly, such as increasing the molecular weight and altering the vibrational modes of the molecule, which can be instrumental in mass spectrometry and NMR spectroscopy. This allows for precise tracking and quantification of the compound in complex biological systems, facilitating detailed studies on its biotransformation and interaction with biological targets. Flecainide-d3 is particularly useful in studies where distinguishing the administered compound from endogenously produced analogues is critical, enhancing the understanding of its mechanistic pathways without interfering with the system′s natural dynamics.
