Additional information

In a study performed according to EU Method A.4 and in accordance with GLP, the vapour pressure of the test substance was determined using the dynamic method (Jackson 2000). Boiling points were determined at five different pressures. An Antoine equation was fitted to the data and the vapour pressure was determined to be 0.04 ± 0.01 kPa at 25 °C.
