Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The substance is not classified as a explosive substance.
Key value for chemical safety assessment
- Explosiveness:
- non explosive
Additional information
The substance is stable at room temperature, however tends to polymerize violently in the presence of impurities. The substance is not sensitive against shock or friction, however explodes under influence of a flame. Explosiveness depends on pressure, temperature, concentration, the type, form, and energy of the ignition source, and the type of container. Decomposition temperature: 571 °C (calculated).
For this reason the substance is classified as a chemical unstable gas that "may react explosively even in the absence of air" H230.
Justification for classification or non-classification
Given that the substance explodes under the influence of a flame, it is classified with H230 "May react explosively even in the absence of air"
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).
