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, enabling precise molecular structure determination. Additionally, it is employed in research and development for studying reaction mechanisms and molecular interactions, particularly in chemistry and biochemistry laboratories. Its application is crucial in fields requiring high-purity solvents for sensitive analytical techniques.
