Additional information

The substance has low logKow (= 2.2) and is gaseous at room temperature. Thus, it is expected to have a low potential for adsorption. The Koc was calculated from the log Kow using the non-hydrophobics QSAR in EUSES: log Koc = 0.52·logKow + 1.02. The calculated Koc value is 146 L/kg. This predicted value is used in the assessment.

The Henry's law constant is calculated in EUSES using the substance's molecular weight of 130.5 g/mol, the experimentally determined vapour pressure of 1065 hPa (at 19.93°C) and the water solubility of 1900 mg/L (at 20°C). The Henry's law constant at environmental temperature (12 °C) is calculated to be 4.64E+03 Pa·m³/mol. Based on this value, the substance is expected to volatilise rapidly from water.
