Description of key information

Water solubility [3-(triethoxysilyl)propanethiol]: 82 mg/l at 20°C (QSAR)
Water solubility [3-(trihydroxysilyl)propanethiol]: very soluble (1E+06 mg/l) at 20°C, (QSAR)

Key value for chemical safety assessment

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

Additional information

In water, 3 -(triethoxysilyl)propanethiol will hydrolysed moderately to form 3-(trihydroxysilyl)propanethiol and ethanol.

A predicted water solubility of 82 mg/l at 20°C was determined for the substance using a validated QSAR estimation method. The result is considered reliable. Similarly, a predicted water solubility value of 1.0E+06 mg/l at 20°C (very soluble) was determined for the silanol hydrolysis product of the substance. Ethanol is miscible with water (Riddick JA 1986)
