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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Two available sources of information (Merck, 2006 & SRC, 2000) were scored 4 for reliability according to the criteria of Klimisch et al, 1997 based on being secondary source information and QSAR (not validated for organometallic substance) respectively. The other two available sources of information were scored 2 for reliability according to the criteria of Klimisch et al, 1997 as both are peer reviewed sources, the NIOSH reference is a goverment report and the other is a CRC handbook. As no one data source was considered robust enough to be considered as a key study a weight of evidence approach was used.
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 135 °C
Additional information
A weight of eveidence approach using the following data gives a result of 135°C at 10 mm Hg (1333.22 Pa).
- In the CRC handbook (Lide, 2009) the boiling point was stated as 135°C.
- In the NIOSH (1978) report the boiling point was stated as 135 °C (275 °F) at 10 mm Hg.
- In the SRC database (2000) the boiling point was reported as 135°C at 10 mm Hg.
Supporting information was also provided in a Merck SDS (2006), where the boiling point was reported as 148 °C at 16 hPa.
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.
