Used primarily as a solvent in nuclear magnetic resonance (NMR) spectroscopy due to its ability to dissolve a wide range of compounds and its deuterated form, which minimizes interference in NMR readings. It is particularly valuable in the analysis of organic molecules, providing clear and precise spectral data. Additionally, it serves as a reaction medium in various chemical syntheses, especially in processes requiring an inert and stable solvent. Its deuterium content also makes it useful in studies involving isotopic labeling, aiding in the tracking and understanding of reaction mechanisms and molecular interactions.
