Description of key information
237.6°C at 1013 hPa (measured)
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 237.6 °C
Additional information
A boiling point value of 237.6°C (at 1013 hPa) was determined by capillary tube method (photocell detection) according to OECD Guideline 103. This is supported by measured values of 235°C (at 1013 hPa) and 112- 113°C (at 10 mmHg) from secondary sources (company data). The supporting results are in good agreement with the key study, but the reliability of the data is unassignable. A boiling point value of 254°C at 1013 hPa was obtained using an accepted calculation method (QSAR).
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).
