Used as a deuterated analog in research and development, particularly in the study of metabolic pathways and drug metabolism. It serves as a stable isotope-labeled compound in mass spectrometry and NMR spectroscopy, aiding in the accurate identification and quantification of substances. Applied in pharmaceutical studies to trace the behavior of its non-deuterated counterpart, helping to understand pharmacokinetics and pharmacodynamics. Also utilized in the synthesis of advanced intermediates for the development of novel therapeutic agents.
