Additional information

In the key study (BASF SE, 2011), the vapour pressure of the test substance was measured to be 3.9E-09 Pa at 20°C and 1.1 E-08 Pa at 25 °C according to OECD guideline 104 and EU Method A.4.

In two further study reports, a vapour pressure of < 0.0000002 Torr (< 0.000026664 Pa) at 45 °C (BASF SE, 1985) and < 0.0000001 Torr (< 0.000013332 Pa) at 60 °C (American Cyanamid Company, 1986) were indicated.

Furthermore, a comparable vapour pressure of 0.000000000179 Torr (0.000000024 Pa) at 25 °C was listed in the HSDB database (HSDB, 2011).
