Description of key information

The vapour pressure of the substance was determined as 3.17 x 10-4 ± 7.02 x 10-6 Pa at 20 degrees Centigrade

Key value for chemical safety assessment

Vapour pressure:
0 Pa
at the temperature of:
20 °C

Additional information

In a GLP, OECD guideline 104 study, spinning rotor gauge (SRG) measurement was initiated with a determination of the offset value, system background pressure and out-gassing rate in the absence of sample. The vacuum system and SRG were then exposed to the test substance until a steady state pressure was obtained. The sample and SRG were then isolated from the vacuum pumps and the pressure increase was monitored by the SRG at 30-second intervals. A linear regression was obtained for pressure increase as a function of time.
