Chlorzoxazone-4,6,7-d3 (CAS 1185173-60-7)

Chlorzoxazone-4,6,7-d3 is an isotopologue of chlorzoxazone where deuterium atoms have replaced hydrogen atoms at the 4, 6, and 7 positions of the aromatic ring. This deuterated compound is often used as an internal standard in analytical studies involving mass spectrometry to ensure precise quantification of chlorzoxazone in biological samples. The presence of deuterium atoms, which are heavier than hydrogen, causes a slight shift in the mass of the molecule, allowing it to be distinguished from non-deuterated chlorzoxazone while retaining similar chemical properties. Researchers employ chlorzoxazone-4,6,7-d3 to study the kinetics and metabolic pathways of chlorzoxazone, as it provides a stable reference point for tracking the parent compound in complex biological systems. The use of this deuterated version is essential for improving the accuracy of detection and measurement in studies that investigate the distribution and elimination of chlorzoxazone in research applications.
