Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Vapour Pressure (EU-method A.4). The calculated vapour pressure is 2.74*10-6 Pa (25 °C)

Key value for chemical safety assessment

Vapour pressure:
0 Pa
at the temperature of:
25 °C

Additional information

The study does not need to be conducted if the melting point is above 300 °C. If the melting point is between 200 °C and 300 °C, a limit value based on measurement or a recognised calculation method is sufficient. "DOPO-OX-Ammonium" decomposed before melting. The decomposed test substance melted in the range of 311 to 330 °C. The vapour pressure of "DOPO-OX-Ammonium" was estimated to 2.74*10-6 Pa at 25 °C (atom/fragment contribution method using the software MPBPWIN).
