Specific details on test material used for the study:
- Lot/batch number of test material: 1903-3/2012
- Purity: not indicated
- Appearance: clear liquid
Key result
20 °C
Vapour pressure:
1 306 Pa
Remarks on result:
other: Mean of 2 runs

Run 1 was performed over a temperature range of 18.2 to 68.7°C. Run 2 was performed over a temperature range of 17.6 to 67.8°C. Vapour pressure curves were constructed (R²=0.9995 and 0.9991 for run 1 and run 2 respectively) and the vapour pressure at 20°C interpolated from the curves.

The vapour pressure of the substance has been reported as 1306 Pa at 20°C.

Description of key information

The vapour pressure of the test substance was determined in a GLP study according to test method EC A.4 to be 1306 Pa at 20 °C, following the isoteniscope method (Younis, 2013).

Key value for chemical safety assessment

Vapour pressure:
1 306 Pa
