物理形态与操作说明

  • Dimethyl sulfoxide appears as a clear liquid, essentially odorless. Closed cup flash point 192 °F. Vapors are heavier than air. Contact with the skin may cause stinging and burning and lead to an odor of garlic on the breath. An excellent solvent that can transport toxic solutes through the skin. High vapor concentrations may cause headache, dizziness, and sedation.

数据库记载的用途

  • Used as a pharmaceutical, a solvent for polymerization and chemical extractions, a paint remover, a preservative for organ transplantation; Occurs naturally in ground water and in grains, vegetables, and many other foods; [CHEMINFO] Used as a solvent for many organic compounds; Also used in industrial cleaners; [HSDB]
  • Semiconductor Manufacturing [Category: Industry]
  • DMSO is not a nutritional supplement. It is used as a treatment for interstitial cystitis, and treatment must be performed by a qualified physician. DMSO is metabolized to methylsulfonylmethane, which is available as a nutritional supplement.
  • Vitrification has become common for cryopreservation of embryos. ...Extended exposure of embryos with both vitrification protocols showed that the DMSO-containing vitrification solutions did not lead to cell membrane damage and death as quickly as the DMSO-free vitrification solutions. To assess embryo viability, the authors recommend that vitrification of early embryos should be combined with extended culture and assessment of normal blastocyst development before transferring to patients.
