Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Key value for chemical safety assessment

Relative density at 20C:
1.159

Additional information

The key value was chosen regarding the most reliable data: the final Risk Assessment Report on Diphenylamine. This value is confirmed by other sources of literature and the results of the guideline study in the DAR 2007 (density: 1.1875).
