Used as a deuterated solvent in nuclear magnetic resonance (NMR) spectroscopy, it helps in analyzing molecular structures by providing a non-interfering background due to its deuterium atoms. It is also employed in research and development for studying reaction mechanisms and kinetics, where the replacement of hydrogen with deuterium allows for precise tracking of chemical processes. Additionally, it serves as a reference standard in analytical chemistry for calibrating instruments and ensuring accurate measurements. Its stability and isotopic purity make it valuable in various scientific investigations requiring labeled compounds.
