Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

Dimethoxydiphenylsilane: 3 mg/l at 20°C (QSAR)
Silanol hydrolysis product: 508 mg/l at 20°C (QSAR)
Methanol): miscible at 20°C

Key value for chemical safety assessment

Water solubility:
3 mg/L
at the temperature of:
20 °C

Additional information

A water solubility of 3 mg/l at 20°C was determined for the substance and 508 mg/l at 20°C for the silanol hydrolysis product using an appropriate calculation method. The results are considered to be reliable.

Methanol is miscible in water at 20°C based on experimental data (OECD 2004).
