Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- Key result
- Atm. press.:
- ca. 101 450 Pa
- Decomposition:
- yes
- Decomp. temp.:
- ca. 203 °C
- Conclusions:
- The test material decomposed from approximately 203 +/- 0.5 oC at 101450 Pa without boilng.
- Executive summary:
The test material decomposed from approximately 203 +/- 0.5 oC at 101450 Pa without boilng.
A determination at reduced pressure was not performed as experience has shown that no further useful information is obtained for test materials which decompose prior to boiling at atmospheric pressures. Secondly suffcient information could be derived from the vapour pressure study to charcterize the high boilng temperature of the test material.
Reference
As a result of the low rate of enthalpy change durng decomposition, the onset temperature can only be approximated. As the test material decomposed, no value for the boilng temperature could be determined. From data obtained in the vapour pressure study (Safepharm Laboratories Project Number 1666/008), the boiling point of the test material is estimated to be >360 oC at 101325 Pa.
A determination at reduced pressure was not performed as experience has shown that no further useful information is obtained for test materials which decompose prior to boiling at atmospheric pressures. Secondly suffcient information could be derived from the vapour pressure study to charcterize the high boilng temperature of the test material.

Additional information
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.
