Levofloxacin-d3 Sodium Salt, is the labeled analogue of Levofloxacin, an antibiotic used against gram-negative organisms. The incorporation of deuterium atoms allows for the distinct identification and quantification of levofloxacin in complex biological matrices. In mass spectrometry (MS), the deuterium-labeled compound provides a unique signal that helps distinguish it from endogenous substances and metabolites, facilitating accurate kinetic analyses. The deuterium atoms in Levofloxacin-d3 sodium salt can be used to study the stability of the molecule under various conditions and to track its metabolic pathways. The kinetic isotope effect, where the presence of deuterium can alter the rate of chemical reactions slightly, enables researchers to understand better how the molecule is processed in biological systems.
