Boiling point
Administrative data
Link to relevant study record(s)
- Endpoint:
- boiling point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2007
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling point/boiling range)
- Deviations:
- no
- GLP compliance:
- yes
- Type of method:
- differential scanning calorimetry
- Boiling pt.:
- 226 K
- Atm. press.:
- 102.14 kPa
- Conclusions:
- The boiling point of the test substance was measured to be 499 ± 0.5 K at 102.14 kPa (226°C), determined in a reliable study according to an appropriate test protocol and in compliance with GLP. The result is considered reliable.
- Endpoint:
- boiling point
- Type of information:
- (Q)SAR
- Adequacy of study:
- supporting study
- Study period:
- 2011
- 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 attached QMRF and QPRF for details)
- Boiling pt.:
- 482 K
- Atm. press.:
- 1 013 hPa
- Boiling pt.:
- 209 °C
- Atm. press.:
- 1 013 hPa
- Conclusions:
- A boiling point value of 209°C has been obtained for the test substance using an appropriate estimation method. The result is considered reliable.

Description of key information
Boiling point (trimethoxyphenylsilane): 226°C at 102.14 kPa (OECD guideline 103)
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 226 °C
Additional information
A boiling point value of 226°C at 102.14 kPa was reported based on a standard guideline study (OECD Guideline 103 Boiling point/boiling range). The result is considered to be reliable and was selected as the key study. A value of 211°C was available in a handbook, to which reliability could not be assigned. A predicted value of 209°C, calculated using a validated predictive method, is also available.
