Used extensively in research and development, particularly in the field of analytical chemistry, where it serves as a deuterated internal standard for mass spectrometry. Its stable isotopic labeling allows for precise quantification and identification of compounds in complex mixtures, making it invaluable in metabolomics and environmental analysis. Additionally, it is employed in nuclear magnetic resonance (NMR) spectroscopy as a solvent or reference compound due to its unique deuterium substitution, aiding in the study of molecular structures and dynamics. Its applications also extend to the pharmaceutical industry, where it is used in drug development and quality control processes to ensure accurate measurement of active ingredients and impurities.
