Endpoint:
water solubility
Type of information:
(Q)SAR
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
results derived from a valid (Q)SAR model and falling into its applicability domain, with adequate and reliable documentation / justification
Justification for type of information:
QSAR prediction
Principles of method if other than guideline:
The result was obtained using an appropriate QSAR method (see QMRF and QPRF for details).
GLP compliance:
no
Water solubility:
110 mg/L
Temp.:
20 °C
pH:
7

Estimated value, no data available for pH.

Conclusions:
A water solubility of 110 mg/l at 20 - 25°C was obtained for the test substance using an appropriate calculation method. The result is considered reliable.

Description of key information

Water solubility (trimethoxy(2,4,4-trimethylpentyl)silane): 110 mg/L (QSAR)
Water Solubility ((2,4,4-trimethylpentyl)silanetriol): 2.4E+05 mg/l (QSAR)
Methanol: miscible at 20°C

Key value for chemical safety assessment

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

Additional information

The requirement to test the water solubility of the substance is waived because in contact with water the substance hydrolyses rapidly. However, the water solubility of the substance and its hydrolysis product was predicted to be 110 mg/l and 2.4E+05 mg/l at 20 - 25°C using a relevant estimation method. The results are considered reliable.

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