Used as a solvent in organic synthesis, particularly in reactions requiring a polar, non-aqueous medium. It is also employed in NMR spectroscopy as a deuterated solvent for analyzing chemical structures. Additionally, it serves as a reagent in the preparation of fluorinated compounds, leveraging its unique trifluoro and deuterium properties. In biochemistry, it is utilized for protein denaturation studies due to its ability to disrupt hydrogen bonding. Its deuterated form is particularly valuable in isotopic labeling experiments for tracing molecular pathways.
