Type of information:
Adequacy of study:
key study
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: The result was obtained by the valid application of an appropriate predictive method.
Justification for type of information:
QSAR prediction: migrated from IUCLID 5.6
Principles of method if other than guideline:
The result was obtained using an appropriate QSAR method (see attached QMRF and QPRF for details).
Boiling pt.:
270 °C
Atm. press.:
ca. 101 kPa
Boiling pt.:
543 K
Atm. press.:
ca. 101 kPa
A boiling point value of 270°C was obtained using an accepted calculation method. The result is considered to be reliable.

Description of key information

Boiling point [3-(2,3-epoxypropoxy)propyl]triethoxysilane: 270°C (QSAR)

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
270 °C

Additional information

A predicted boiling point of 270°C (543K) was determined for the substance using a validated QSAR estimation method. The result is considered to be reliable.
