Additional information

A study was conducted. The study was conducted equivalent or simailar to the OECD Guideline for the Testing of Chemicals 104: "Vapour pressure" using the dynamic method. The vapour pressure of the substance was determined to be 0.38 hPa at 20 °C, 0.56 hPa at °C and 3.23 hPa at 50 °C. This was supported by several literature sources and a an elder non-GLP study. The non-GLP study reported the vapoure pressure of the substance to be 3.5 mBar at 50 °C. The GESTIS - Substance database and the Handbuch der gefährlichen Güter reported the vapour pressure to be 0.5 hPa at 20 °C. The value from the latest study was chosen as key value for the boiling point.
