Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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: Non explosive (EU Method A.14)
Key value for chemical safety assessment
- Explosiveness:
- non explosive
Additional information
No explosivity data are available for the submission substance, 2-(3,4-epoxycyclohexyl)ethyltrimethoxysilane (CAS No: 3388-04-3), therefore reliable data for the analogue substance 3-(2,3-epoxypropoxy)propyl]trimethoxysilane (CAS No: 2530-83-8) have been read-across. Both substances are trimethoxysilanes containing an epoxy functional group attached to the silicon side chain. The calculated oxygen balance of 2-(3,4-epoxycyclohexyl)ethyltrimethoxysilane was -188 and that of its structural analogue was -156. [3-(2,3 -Epoxypropoxy)propyl]trimethoxysilane was found to be not explosive in a reliable standard study conducted in accordance with EU Method A.14. It can therefore be concluded that the presence of an epoxy 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 IUCLID dataset.
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.
