Used in research and development as a labeled compound for studying metabolic pathways and enzyme mechanisms. It is particularly valuable in pharmacokinetics and drug metabolism studies, where deuterium labeling helps track the compound’s behavior in biological systems. Also employed in analytical chemistry as an internal standard in mass spectrometry for accurate quantification of similar compounds in complex mixtures. Its application extends to neuroscience research, where it aids in investigating the role of specific biochemical pathways in brain function and disorders.
