Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Bp (DSC): Decomposition of substance >470 K (197 °C); calculated (MPBPWIN, US EPA) Bp = 254 °C at atmospheric pressure, EU Method A.2, Walker 2007
Bp (Siwoloboff): 255 °C at atmospheric pressure, EU Method A.2, Swioloboff, Walker 2007
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 255 °C
Additional information
The boiling temperature was determined using EU Method A.2 and OECD Method 103 and ASTM E537-86. As the substance decomposed, no value for the boiling point could be determined experimentally. A similar degradation profile was obtained using nitrogen atmosphere; this would indicate that the observed decomposition is probably thermal and not oxidative. The substance has been determined to decompose from 470 K (197°C) at 101.0 kPa, with no indications of boiling below 573 K (300°C). As the substance decomposed, no value for boiling point could be determined. A calculated value of boiling point gave a result of 527 K (254°C) using an adaptation of the Stein and Brown Method MPBPWIN version 1.42, ©2000 U.S. Environmental Protection Agency.
The boiling temperature was determined via the Siwoloboff methodology equivalent to EU Method A.2 and OECD Method 103. No decomposition was reported during the test. The boiling temperature of the substance has been determined to be 527 K (254 °C) at 986 mBar. The BP (Siwoloboff) = 255°C corrected to atmospheric pressure (1013mBar).
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.
