Description of key information

The density of dimethyl sulphate is 1.33 g/cm3 at 20 °C.

Key value for chemical safety assessment

Relative density at 20C:

Additional information

A literature review was conducted. In a weight of evidence approach the literature values were evaluated. REAXYS reports the density to be between 1.332 g/cm3 and 1.3283 g/cm3 at 20 °C. HSDB reports the density to be 1.3322 g/cm3 at 20 °C.

The GESTIS database reports the density to be 1.33 g/cm3 at 20 °C and IPCS International Programme on Chemical Safety reports the relative density to be 1.3 at 20 °C. Four independent literature sources reports the density in the same range. Thus, a density of 1.33 g/cm3 at 20 °C which represent the median of all values was chosen as key value.
