Key value for chemical safety assessment

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

Additional information

Based on the isothermal TGA effusion method applied on 3,3'-DDS and the read-across approach, the vapour pressure for 4,4'DDS can be estimated to be < 1.5.10-3 Pa at 20°C (293K) and < 4.2.10-3 Pa at 25°C (298K).
