Additional information

A GLP study was conducted. BASF GLP study no. 15L00003 in accordance with the OECD Guideline for the Testing of Chemicals 104: "Vapour pressure" by the gas saturation method, weight loss. The vapour pressure of the substance was determined to be 0.014 hPa at 20°C, 0.023 hPa at 25 °C and0.2 hPa at 50 °C.
