Used extensively in nuclear magnetic resonance (NMR) spectroscopy as a reference compound due to its deuterated form, which provides a clear and distinct signal. It is particularly valuable in studies involving the analysis of molecular structures and dynamics in various chemical and biological systems. Additionally, it serves as a useful reagent in organic synthesis, especially in reactions where isotopic labeling is required to trace pathways or mechanisms. Its application extends to pharmaceutical research, where it aids in the development and testing of new drugs by providing insights into metabolic processes and interactions at the molecular level.
