Used in research and development as a stable isotope-labeled compound, it serves as a tracer in metabolic studies to track biochemical pathways and drug metabolism. It is also employed in nuclear magnetic resonance (NMR) spectroscopy to enhance the resolution and accuracy of molecular structure analysis. Additionally, it finds application in environmental science for studying the fate and transport of organic compounds in ecosystems. In pharmaceuticals, it aids in the synthesis of deuterated drugs, which can improve pharmacokinetic properties and reduce side effects. Its use in analytical chemistry ensures precise quantification and identification of complex mixtures.
