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 environment for precise molecular structure determination. Additionally, it is employed in research and development for studying chemical reactions and mechanisms, particularly in fields like organic chemistry and material science. Its application extends to specialized industrial processes where a deuterated compound is required for specific analytical or synthetic purposes.
