Dimethyl sulfoxide-d6
CAS: 2206-27-1
Category: Organosulfur Compounds
| Purity | 99.9 atom % D (deuterium enrichment), 99.8 atom % D, 99.5 atom % D, 99 atom % D; typically with wate |
| Molecular Formula | C2H6OS |
| Molecular Weight | 84.17 |
| Appearance | Colorless to pale yellow clear liquid (hygroscopic) |
| Packaging | 0.5mL/1mL/5mL/10mL/25mL/50mL/100mL/glass ampoule or serum bottle with PTFE-lined septum; 1kg/bottle for bulk research use |
| Testing Indicators | Appearance — Visual inspection; Deuterium enrichment — ¹H NMR or mass spectrometry (percentage of D atoms); Purity (isotopic) — ¹H NMR integration; Water content — Karl Fischer titration; Residual protonated DMSO — ¹H NMR (integration of CH₃ signal vs. CD₃); Identification — FTIR or NMR; Refractive index — Refractometry; Density — Digital densitometer; Boiling point — Distillation method. |
| Storage Notes | Stored in a tightly sealed container (PTFE or glass) under inert atmosphere (argon or nitrogen) in a cool, dry, well-ventilated area, protected from light and moisture (highly hygroscopic); away from strong oxidizers, strong acids, and heat sources; store at room temperature; avoid prolonged exposure to air as D₂O absorption will occur. |

Used as a deuterated solvent for nuclear magnetic resonance (NMR) spectroscopy, particularly for polar and water-soluble organic, inorganic, and biological compounds; provides a residual solvent peak at approximately 2.50 ppm in ¹H NMR and 39.5 ppm in ¹³C NMR; also used in mechanistic studies involving isotope effects; and as a solvent for reactions requiring deuterium labeling or where proton interference must be minimized.
