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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Explosiveness: Not explosive
Key value for chemical safety assessment
- Explosiveness:
- non explosive
Additional information
The molecule has no chemical groups that are associated with explosive properties. Therefore, in accordance with Column 2 of REACH Annex VII, there is no need to conduct the explosive properties study. However, like many chlorosilanes, it has an oxygen balance above -200. Experimental explosivity data is read-across from trichloro(methyl)silane (CAS 75-79-6). The calculated oxygen balance for the registered substance 1,2 -bis[dichloro(methyl)silyl]ethane is -81 and that of trichloro(methyl)silane is -37. Trichloro(methyl)silane was found to be not explosive in a reliable standard study (EU Method A.14). It can therefore be concluded that the presence of chloro group in an organosilicon compound is not associated with explosive properties. Additional information is given in a supporting report (PFA 2013c) attached in Section 13 of the REACH technical dossier.
The read-across is therefore indicative of the substance not inherently possessing the capacity to exhibit the explosivity hazard. In addition, it is an inorganic substance lacking oxygen.
Justification for classification or non-classification
There is no evidence to suggest that the substance should be classified for this endpoint.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
