at the temperature of:
20 °C

Additional information

A non-GLP study and a literature review was conducted. In a weight of evidence approach the values were evaluated. The study determined the vapour pressure to be 38.9 hPa at 20 °C and 122.7 hPa at 50 °C. The Syracuse Research Coperation, Physical Properties Database reported the vapour pressure to be 39 hPa at 20 °C. The GESTIS database reported the vapour pressure also to be 39 hPa at 1013 hPa and the Hazardous Substances Data Base reported the vapour pressure to be between 39 hPa and 40 hPa at 20°C. They all reported the density in the same range and regarded to be reliable for the substance. The vapour pressure of the study was chosen as key value.
