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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Results and discussion
For thermal stability study
- Test substance thermally stable:
- yes
Any other information on results incl. tables
No spontaneous decomposition and no decomposition air-dependent.
Applicant's summary and conclusion
- Conclusions:
- No spontaneous decomposition and no decomposition air-dependent.
- Executive summary:
Dynamic decomposition test was run with the test substance. The air dependence of the thermal decomposition is determined using the test RADEX dynamically with air flush. The test method is commonly used in other than REACH Regulation context and it can be considered as scientifically acceptable. Nevertheless, only the test sheet is available.
Conclusion
No spontaneous decomposition and no decomposition air-dependent.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
