Description of key information

Log Kow (substance): 2.0 at 20°C
Log Kow (silanol hydrolysis product): -1.1 at 20°C

Key value for chemical safety assessment

Log Kow (Log Pow):
at the temperature of:
20 °C

Additional information

The requirement to test the substance for octanol-water partition coefficient is waived because in contact with water the substance rapidly hydrolyses to 3-chloropropylsilanetriol and methanol. The Log Kow of the substance and the silanol hydrolysis product have been calculated using validated QSAR.
