CAS 67-68-5 Dimethyl sulfoxide (DMSO) is a solvent that is used in industry and in pharmaceuticals. It is known for being stable and for dissolving many substances. Two of its most important physical properties are its boiling point and density. These directly affect how easily it can be stored, handled, and applied.
Boiling Point of DMSO
The boiling point of dimethyl sulfoxide DMSO is: 189 °C (372 °F) at standard atmospheric pressure.
At standard atmospheric pressure (760 mmHg), the boiling point of pure DMSO is 189°C. This high boiling point gives DMSO excellent thermal stability, allowing it to remain a stable liquid in intermediate-temperature chemical reactions and preventing it from easily volatilizing.
Density of DMSO
The density of DMSO is 1.100 g/cm³ at 20℃.
DMSO chemical has a slightly higher density than water, and its density varies with temperature. The density of DMSO decreases slightly with increasing temperature. DMSO is completely miscible with water, ethanol, and most organic solvents; its density data is a crucial basis for calculating solution ratios in pharmaceutical and biochemical experiments.
