Montelukast-d6, is the labeled analogue of Montelukast, a selective leukotriene D4-receptor antagonist. Montelukast-d6 can be used as an internal standard in mass spectrometry-based assays to accurately measure the kinetics of montelukast. The deuterated version helps in distinguishing the compound from its metabolites and quantifying it in biological samples without interference from the non-deuterated compound. It provides a tool for studying the metabolism of montelukast, as the presence of deuterium can influence the rate of metabolic reactions (kinetic isotope effect). This can offer insights into how the compound is processed in biological systems.
