Used as a labeled compound in research and analytical studies, particularly in mass spectrometry and nuclear magnetic resonance (NMR) spectroscopy. It serves as a tracer or internal standard in experiments to study metabolic pathways, reaction mechanisms, or environmental processes. Its deuterated structure allows for precise tracking and detection in complex chemical or biological systems. Applied in pharmaceutical development to investigate drug metabolism and pharmacokinetics. Also utilized in environmental science to trace the behavior of organic compounds in ecosystems. Its stability and isotopic labeling make it valuable for advanced scientific investigations.
