Description of key information
The information is based on different secondary sources with consistent values for boiling point of the substance ranging from 299 - 302 °C.
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 302 °C
Additional information
The key value for the boiling point was chosen according to the most reliable data: the final Risk Assessment Report on Diphenylamine. This value was also found in other sources of literature, and confirmed by the results of the guideline study in the DAR 2007 (boiling point: 298.8°C)
