Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Any other information on results incl. tables

The calculations shown that dimethyl sulfate does not contain any structural groups known to be correlated with a particular explosion hazard. In addition, the thermodynamic calculations presented above indicate that the heat of decomposition and the comparison to the heat of combustion does not necessitate explosivity to be expected. Finally, the oxygen balance is negative. In conclusion, structural aspects and estimated thermodynamic properties indicate that dimethyl sulfate must not be considered to have explosive properties.

Applicant's summary and conclusion

Conclusions:
In conclusion, structural aspects and estimated thermodynamic properties indicate that Dimethyl sulfate must not be considered to have explosive properties.
Executive summary:

The thermodynamic calculations presented above indicate that the heat of decomposition and the comparison to the heat of combustion does not necessitate explosivity to be expected. However, the value for the oxygen balance (-63%) in combination with the presence of groups which are able to contribute to the explosive properties gives any doubt. Nevertheless, as stated above experience has shown that this value is primarily of relevance for compounds consisting of C, H, N and O.

According to the EU risk assessment report, 2002 it is stated that the substance is not associated to be explosive, based on chemical structure.

 

In conclusion, structural aspects and estimated thermodynamic properties indicate that Dimethyl sulfate must not be considered to have explosive properties.
