Used primarily as a solvent and reagent in organic synthesis, it is particularly valuable in NMR spectroscopy as a deuterated solvent for analyzing non-polar compounds. Its deuterium substitution minimizes interference in spectral analysis, making it useful in research and development for studying molecular structures. Additionally, it serves as a reference standard in analytical chemistry for calibration and validation purposes. In industrial applications, it is employed in the production of specialty chemicals and pharmaceuticals, where precise deuterium labeling is required. Its non-reactive nature under certain conditions also makes it suitable for use in specific chemical reactions requiring inert environments.
