Description of key information
Boiling point: 260°C at 1013 hPa (EU Method A.2)
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 260 °C
Additional information
Two reliable measured boiling point studies are available for the submission substance. A measured boiling point value of 260°C (533 K) at 1013 hPa was determined for the submission substance using a method according to Siwoloboff test method according to EU Method A.2 and in accordance with GLP. The result is considered to be reliable and is selected as key study.
In the supporting study, a boiling point value of 257°C (533 K) at 1013 hPa was determined for the substance using a photocell detection method in accordance with EU Method A.2 and in compliance with GLP. The supporting study is in good agreement with the key value.
In a secondary literature to which reliability could not be assigned, boiling point value of 120°C at a lower pressure of 6 mmHg was reported for the substance.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
