Used as a solvent in organic synthesis, particularly for reactions involving peptides and proteins due to its ability to solubilize these biomolecules. It is also employed in nuclear magnetic resonance (NMR) spectroscopy as a deuterated solvent, aiding in the analysis of molecular structures. Additionally, it serves as a reagent in the preparation of fluorinated compounds, which are valuable in pharmaceuticals and agrochemicals. Its properties make it useful in the study of protein folding and stability, as it can mimic the hydrophobic environment of biological membranes.
