Used primarily as a solvent in nuclear magnetic resonance (NMR) spectroscopy, it serves as a deuterated solvent for analyzing organic compounds. Its deuterium atoms provide a stable and non-interfering background in NMR experiments, making it ideal for studying molecular structures and dynamics. Additionally, it is employed in research settings where non-deuterated solvents would interfere with the analysis. Its application extends to the synthesis of deuterated compounds, aiding in the study of reaction mechanisms and isotopic effects.
