QUICK LINKS

Rifaximin-d6 is a deuterated version of rifaximin. This modification is generally used to enhance the analytical characteristics of the compound. Deuterium substitution can enhance the metabolic stability of chemical compounds, making rifaximin-d6 potentially more resistant to metabolic degradation than its non-deuterated counterpart. Rifaximin-d6 is valuable in kinetic research to trace the absorption, distribution, metabolism, and excretion (ADME) of rifaximin in biological systems. The deuterated markers make it easier to distinguish the metabolites of the compound from other substances in the system. Using deuterated standards such as rifaximin-d6 in mass spectrometry enhances the accuracy and reliability of analytical methods, reducing background noise and improving signal clarity.
